Sets a preference for when Auto-Configuration configures the virtual MLAG ID. The default (cascade) configures the virtual MLAG ID whenever a 2nd-tier BPE is detected remotely, but not locally.
| vpex | Specifies Virtual Port Extender (VPEX). |
| auto-configuration | Specifies the VPEX Auto-Configuration of cascade ports and VPEX slots. |
| mlag-id | Specifies setting a unique MLAG identifier of the MLAG port attached to the bridge port extender (BPE). |
| cascade | Specifies to configure the virtual MLAG identifier when a 2nd-tier BPE is detected on the other controlling bridge, but not locally (default). |
| ring | Specifies to configure the virtual MLAG identifier when a ring is detected. |
cascade.
The ring option provides more cabling time if you need to cable the chain of BPEs as duel-homed instead of single-homed.
This command is applicable only when VPEX Auto-Configuration is enabled in MLAG mode.
# configure vpex auto-configuration mlag-id cascade
The following example displays output when VPEX Auto-Configuration is not enabled in MLAG mode:
# configure vpex auto-configuration mlag-id ring Error: VPEX Auto-Configuration is not in MLAG mode. Bring up MLAG peer, disable then re-enable VPEX Auto-Configuration.
This command was first available in ExtremeXOS 31.7.
This command is available on ExtremeSwitching 5420 and 5520 series switches, and Extreme 7520-48Y switches.
