Virtual Link Aggregation Group (Vlag) Configuration - Lenovo RackSwitch G8332 Command Reference Manual

Virtual Link Aggregation Group (vLAG) Configuration

© Copyright Lenovo 2016
Virtual Link Aggregation Groups (vLAGs) allow you to enhance redundancy and
prevent implicit loops without using STP. The vLAG acts as a single virtual entity
for the purpose of establishing a multi‐port Link Aggregation Group (LAG).

vLAG Configuration Options
Command Syntax and Usage
[no] vlag adminkey <1‐65535> enable
Enables or disables vLAG on the selected LACP admin key. LACP LAGs
formed with this admin key will be included in the vLAG configuration.
Command mode: Global configuration
vlag auto­recovery <240‐3600>
Sets the duration in seconds of the auto‐recovery timer. This timer configures
how log after boot‐up configuration load, the switch can assume the Primary
role from an unresponsive ISL peer and bring up the vLAG ports.
The default value is 300 seconds.
Command mode: Global configuration
no vlag auto­recovery
Sets the auto‐recovery timer to the default 300 seconds duration.
Command mode: Global configuration
[no] vlag enable
Enables or disables vLAG globally.
Command mode: Global configuration
[no] vlag mac­address­table refresh
Enables or disables the periodic check of the aging status of synchronized
Forwarding Database (FDB) entries. When a MAC address is marked for
removal from the FDB table, the entry is reinstalled instead.
The default setting is enabled.
Note: This option takes effect only if the aging value for FDB entries is set to 40
seconds or more. For more details on FDB aging, see page
Command mode: Global configuration
[no] vlag peer­gateway
Enables or disables the forwarding of packets intended for the switch's vLAG
peer. If a packet is received by the switch, but has the MAC address of its
vLAG peer, it will be locally forwarded without crossing the vLAG
inter‐switch link (ISL), thus avoiding the loss of traffic.
If the vLAG peer gateway is disabled, packets addressed to the vLAG peer are
sent across the ISL and then dropped by the vLAG peer.
The default settings is disabled.
Note: The vLAG peer gateway must be configured on both vLAG peers.
