Step Command Remarks
3. Enable the RR mode for the
S-channel.
evb reflective-relay
By default, the RR mode is
disabled for an S-channel.
Configuring MAC address learning for an S-channel
You can manually disable the MAC address learning function for an S-channel by performing this task.
Follow these restrictions and guidelines when you configure MAC address learning for an S-channel:
• For an S-channel with the RR mode disabled, do not disable its MAC address learning function.
Otherwise, the bridge might fail to forward traffic for VMs on the EVB station.
• After you disable the MAC address learning function for an S-channel, the bridge will discard
packets with an unknown source MAC address.
• The undo evb mac-learning forbidden command and the mac-address mac-learning enable
command must be configured together to avoid communication interruption. For more information
about the mac-address mac-learning enable command, see Layer 2—LAN Switching Command
References.
To disable MAC address learning for an S-channel:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter S-channel interface
view or S-channel aggregate
interface view.
interface { s-channel |
schannel-aggregation }
interface-number:channel-id
N/A
3. Disable MAC address
learning for the S-channel.
evb mac-learning forbidden
By default, the MAC address
learning function is enabled for an
S-channel.
Configuring a VSI interface or VSI aggregate
interface
Creating a VSI interface or VSI aggregate interface
IMPORTANT:
When the total number of VSI interfaces and VSI aggregate interfaces on the device exceeds 512, make
sure the VDP keepalive exponent is larger than the default value. Otherwise, some VSI interfaces or VSI
aggregate interfaces might be automatically deleted.
A VSI interface is created on an S-channel interface through this task, and it is a subinterface of the
S-channel interface. A VSI aggregate interface is created on an S-channel aggregate interface, and it is
a subinterface of the S-channel aggregate interface. Removing an S-channel also removes all its VSI
interfaces and VSI aggregate interfaces.
