You can use the CLI, SNMP, and any of the supported network management applications. You manage the switch stack and the stack member interfaces through the active switch. To be upgraded to a compatible software version so that it can join the switch stack. The auto-upgrade and auto-advise features enable a switch with software packages that are incompatible with the switch stack Upgrading a Switch Running Incompatible Software This avoids Link Aggregation Control Protocol (LACP) and Port Aggregation Protocol (PAgP) flaps or inconsistencies. You can also configure stack MAC persistency so that the stack MAC address never changes to the new active switch MAC address, by using the stack-mac persistent timer 0 command. The stack MAC address will be the MAC address of the first active switch, even if a new active switch takes over. If the previous active switch does not rejoin the stackĭuring this period, the switch stack takes the MAC address of the new active switch as the stack MAC address.
Period, if the previous active switch rejoins the stack, the stack continues to use its MAC address as the stack MAC address,Įven if the switch is now a stack member and not an active switch. You can use the persistent MAC address feature to set a time delay before the stack MAC address changes. Persistent MAC Address on the Switch Stack
The active switch contains the saved and running configuration files for the switch stack. Interface-level features for each stack member System-level (global) features that apply to all stack members The active switch controls the operation of the switch stack, and is the single point of stack-wide management. LayerĢ and Layer 3 protocols present the entire switch stack as a single entity to the network. The stack members work together as a unified system. Upgrading a Switch Running Incompatible SoftwareĪ switch stack can have up to eight stacking-capable switches connected through their StackWise ports.
#LOOPBACK CABLE ON SWITCH LICENSE#
You cannot have a switch stack containing a mix of different license levels.ĭo not stack Cisco Catalyst 9200L Series Switches with Cisco Catalyst 9200 Series Switches.Ĭ9200-24PB and C9200-48PB switch models can only be stacked with each other and not with other models of the Cisco Catalyst Only homogenous stacking is supported, that is, a stack of Cisco Catalyst 9200 Series Switches with only Cisco Catalyst 9200 Series Switches as stack members. The following are the restrictions for switch stack configuration:Ī switch stack can have up to eight stacking-capable switches connected through their StackWise ports. See the System Management section of this guide.Īll the switches in the switch stack must be running compatible software versions.
