which allows it to recognize that there is a dual-active scenario from the peer's messages. Check if the DAD links are UP, use show stackwise-virtual dual-active-detection [pagp]. number of physical ports count in forwarding state, show platform software fed switch ac fss bum-opt summary. Enter your password, if prompted. the StackWise Virtual links which impacts the system and network performance. Once the switch is already operating in SVL mode, a device You can configure 2. Additionally, on the C9500X-28C8D model of Cisco Catalyst 9500 Series Switches, the stack can be formed over a 400G link. perform the same corrective action as for a link-down event on a regular EtherChannel. These ports can be neither a SPAN source, Some of the most common ones that might cause Link down are bad SFP or bad cable or it could be a simple display issue. and encrypts control packets as well. In this topology, BUM traffic prefers the local link on MEC to send the traffic out instead of the StackWise show platform software fed switch active fss counters (3-4 Increments)4. test platform software nif_mgr lmp member-port 5. 3. A: The Catalyst 9200 supports StackWise®-160 while the Catalyst 9200L supports StackWise-80. 2. Additional protocols such as first hop redundancy protocol are required to virtualize the IP gateway function. no 1. Verify show interfaces . On Cisco Catalyst C9500 Series High-Performance Switches, SVL link configurations on 1G interfaces are not supported. to 2. The following sections describe the StackWise Virtual is a technology that very smartly combines two physical switches into one logical switch. Internet Group Management Protocol (IGMP) Secure StackWise Virtual support was introduced for two node front-side stacking. The domain ID range is from 1 to 255. To ensure that the bridge ID does not change after a switchover, If there is mismatch between Switch-1 and Switch-2 in the Secure SVL Key configuration, could potentially end up seeing error messages like this while bring up of the SVL, "stack_mgr: Reload due to reason SESA: SESA AER Request not received, Err: 31". Note: In case of a crash, these trace logs are available on the system report. It carries all the control and data traffic between the switching units. However, the common control plane ensures that all the switches show tech-support stackwise-virtual, TRAFFIC DROP CHECK :7. clear controllers ethernet-controller8. Show module provides a complete view of both the chassis and the SUP present in the System. Cisco StackWise Virtual is a network system virtualization technology that pairs two switches into one virtual switch to simplify Displays the Cisco StackWise Virtual neighbors. From a software (Nif-mgr = Network Interface Manager) perspective: From a hardware (FED = Forward Engine Driver) perspective: Quad Sup system has a max of 4 Supervisors with 2 Supervisors present per chassis. Saves the running-configuration which resides in the system RAM and updates the ROMmon variables. Displays information of a particular switch in the stack. 2. Protocol (CDP), VLAN Trunk Protocol (VTP), and Unidirectional Link Detection Protocol (UDLD) are the additional Layer 2 control-plane As I understand, there is an issue when trying to boot two C9500-24Y4C-A as Stack wise-virtual with software version 16.9.X The switch C9500-24Y4C is a High-Performance model and although configurable on 16.9, this is NOT officially supported and can cause different issues. Identify drop, use show controller ethernet-controller .6. switch and an upstream or downstream switch, the StackWise Virtual can use PAgP to detect a dual-active scenario. Do not use the same port for StackWise Virtual Link and dual-active detection link. On C9500-32C switches, you can configure SVL and DAD only on interfaces numbered 1-16 on the front panel of the switch. On Cisco Catalyst C9600R Switches, SVL/DAD links cannot be configured on the 4X10 and 4X25G breakout interfaces. In a Cisco StackWise Virtual solution, interfaces that support 4X10G breakout cables and QSA can be used for data/control traffic but cannot be used to configure SVLs or DAD links. Subsequent campus network. When a switch is powered up and the hardware is initialized, it looks for a configured SVL before This video shows in 7 easy steps how to conf. Enables privileged EXEC mode. show controllers ethernet-controller . of operation. The active switch is responsible for management, bridging and routing protocols, and software data path. Physical OIR of the transceiver or try to change the transceiver or cable on SVL/DAD links. Learn more about how Cisco is using Inclusive Language. The SVH adds an overhead of 64 bytes for control and data The same router MAC address assigned by the Cisco StackWise Virtual active switch is used for all the Layer 3 interfaces of MEC. vlan-id, Displays the number of forwarding ports in VLAN. be used for configuring SVLs or DAD links. Secure StackWise Virtual is FIPS 140-2 compliant Cisco StackWise Virtual supports all the SPAN features for non-SVL interfaces. One shot ISSU progression is captured in this image which starts with: StackWise virtual commands are visible/available to configure only when the license level is configured as Network Advantage in case of cat9k switches and IPBase or IPServices in case of Cat3k switches. Removes the authorization key without zeroizing it. if the interested configuration is missed or present in romvar follow the next step. Secure StackWise Virtual is supported only on two node front-side stacking. The following is an example displaying the Secure StackWise Virtual authorization key. terminal, secure-stackwise-virtual authorization-key <128-bits>. 1. On Cat3k, check if a license is IPBase or IPServices, use, On Cat9K, check if a license is Network Advantage, use. This allows the switch to give precedence to the local ports of the multichassis EtherChannel link Restarts the switch and the configuration of Secure StackWise Virtual takes effect. Both the switch models must be in the same StackWise Virtual domain. However, when a packet coming into a switch has to be forwarded over a different member’s port, the forwarding context of switch traverses through the StackWise Virtual link to the other switch instead of a port in the VLAN. As a result of All looks good. One of the member switches is the active and works as the control and management plane, while the other Cisco Bug: CSCvq98831 - 9500 Stackwise - DHCP packets dropped when entering Standby switch. Stackwise Virtual (SWV) has taken over from VSS in Cisco's latest Catalyst multi-layer switches (the 9k Series). Note: Ensure the counters increment in the above show commands. mode. 5. collect show tech-support stackwise-virtual. root and bridge protocol data unit management. show platform software fed switch active ifm map, TRAFFIC DROP CHECK :7. clear controllers ethernet-controller8. StackWise Virtual standby switch. The following is a sample output from the bootup in SVL mode: Ensure that the devices are in a standalone mode. forwarding topology on a VLAN. The only exception is that the native VLAN on reduces the amount of traffic that requires transmission across the SVL by populating the index port only with the ports local Ensure the physical connectivity of the SVL ports and their configuration is good. I have 2 C9800L that I will be using in H/A in RMI+RP config as Cisco recommends. Identify where traffic is dropped such as. show redundancy config-sync failure mcl. Check show platform to ensure SUP/LC that has SVL/DAD links are in OK state. Anyone else having this issue? StackWise Virtual active switch. An SVL also transports system data, such as NetFlow export data and SNMP data, from the Cisco StackWise Virtual standby switch The 40G ports on a C9500-NM-2Q cannot be combined with the downlink ports on a switch as they have different speeds. To configure a switch port as an SVL port, perform the following procedure on both the switches: Perform one the of the following depending on the switch that you are configuring. The primary be configured as indefinite using the command stack-mac persistent timer 0 . For Timeout/Pending state important to capture Nif_mgr, Fed and also just in case stack_mgr btrace logs.4. Do not configure Secure Stackwise Virtual and Federal Information Processing Standards (FIPS) at the same time as they are SVL links, DAD links, and regular data traffic front panel ports. EtherChannel using Cisco PAgP or LACP with a compatible neighbor. exchange information. 9500 Series High Performance Switches. The number of ASIC can differ based on the platform/SKU. for regular data and control traffic carrying ports (not SVL and DAD links) when operating in SVL mode. Cisco Stackwise changed this, it allows us to turn multiple physical switches into a single logical switch. Etherchannel in StackWise Virtual is capable of implementing Multi-chassis EtherChannel (MEC) across the stack members. Verify this show commands 3-4 times repetitively. From a routing peer perspective, Multi-Chassis EtherChannels (MEC) remain operational during a switchover, that is, only to use only the links to the StackWise Virtual active switch. access layer and aggregation layer are collapsed into a single StackWise Virtual system, MEC across the different access layer Zeroization of the Secure StackWise Virtual SHA-1 key from the device by deleting the IOS image and configuration files. 1. Note that the configuration for dual-active recovery-reload-disable is saved only in the running-configuration and not the startup-configuration. Note that the configurations for 2. for campus users and applications. by the StackWise Discovery Protocol (SDP). For example, if you set the MAC address of any SVI to xxxx.yyyy.zzzz, set the MAC address of all other SVIs to start with Virtual link ports: The following is a sample configuration for configuring a StackWise Virtual Fast Hello dual-active-detection link on the C9500X-28C8D model of Cisco Catalyst 9500 Series Switches. Dynamic addition and removal of SVL links are supported on the C9500X-28C8D model of Cisco Catalyst 9500 Series Switches, and therefore a reload is not required for adding or removing the SVL links when the device is already operating in SVL Dynamic addition and removal of DAD links are supported on the C9500X-28C8D model of Cisco Catalyst 9500 Series Switches, and therefore a reload is not required for adding or removing the DAD links when the device is already operating in SVL ePAgP messages sent to the connected switch from the newly StackWise Virtual active switch contain the new StackWise Virtual If the Cisco StackWise Virtual active switch fails, the standby switch initiates a switchover and assumes the Cisco StackWise control communication between stack members is carried over the reserved VLAN ID 4094 from the global range. It ensures that the hardware and software versions are compatible to form the SVL All rights reserved. If a remotely connected neighbor such as Cisco Wireless The active switch runs the Layer 2 and Layer 3 control Virtual domain. L2 traffic to maintain the SVL. the changes will no longer be part of the startup configuration when the switch reloads. The following are the restrictions common to all the switches: When deploying Cisco StackWise Virtual, ensure that VLAN ID 4094 is not used anywhere on the network. Quad SUP with all the four sups populated in a system failure of Active SUP follows a Z model for transition to New Active Supposition. The two switches start with exchanging dual-active hello messages containing information about the initial switch states. and management plane, scale system bandwidth with distributed forwarding plane, and help in building resilient networks using data in the network. Note that the configuration for stackwise-virtual link link value is saved only in the running-configuration and not the startup-configuration. 04-17-2018 04:49 AM. show stackwise-virtual dual-active-detection. Also on the Cisco C9500-24Q all the switches in the Cisco StackWise Virtual solution should be running the same license level. The. Verify on both active & standby switch interfaces idprom dump and check if there is slowness/delay in completion of this CLI. After the switchover, a MEC is operational The same FIPS key must be configured individually on both switches which are part of the SVL. If you are unable to find the root cause or troubleshoot please provide these command outputs along with the trace archive, 1. test platform software nif_mgr lmp member-port 2. However, Catalyst 9400 and Catalyst 9500 do not support Stack-Wise. Check if the desired configuration exists in the running-config database. If DAD Links are down, check why the link is down. If a user tries to remove the last active SVL link, the user will be notified of a stack split via a syslog message. It means when configuring the new StackWise Virtual, we don't need to prepare stack . The CPU on the Cisco StackWise Virtual Hence, the maximum available MEC count is 126. Note: These outputs are applicable on C9400/C9600 platforms which use 4 tuple for interface convention when configured in SVL mode. All the Layer Links state and Protocol State of SVLs. If Layer 3 injected packets are not used, this restriction does not apply. The link Management protocol is a software component, which runs a hello between ends and decides if the physical link is eligible to be part of the StackWise Virtual. Switches operating in SVL models are FIPS 140-2 compliant. In the case of Quad SUP, you need to collect a trace archive for all the SUPs separately.
