73-5 config rspan vlan
Description
This command is used by the source switch to configure the source setting for the RSPAN VLAN.
The redirect command is used by the intermediate or last switch to configure the output port of the
RSPAN VLAN packets, and makes sure that the RSPAN VLAN packets can egress to the redirect
ports. In addition, the VLAN setting must be correctly configured to make the RSPAN VLAN work
correctly. That is, for the intermediate switch, the redirect port must be a tagged member port of
the RSPAN VLAN. For the last switch, the redirect port must be either a tagged member port or an
untagged member port of the RSPAN VLAN based on the users’ requirements. If untagged
membership is specified, the RSPAN VLAN tag will be removed. The redirect function will only
work when RSPAN is enabled. Multiple RSPAN VLANs can be configured with the redirect setting
at the same time.
A RSPAN VLAN can be configured with the source setting and the redirect setting at the same
time.
Format
config rspan vlan [vlan_name <vlan_name> | vlan_id <vlanid 1-4094>] [redirect [add | delete]
ports <portlist> | source {[mirror_group_id <value 1-4> | [add | delete] ports <portlist> [rx |
tx | both]]}]

vlan_name - Specify the RSPAN VLAN by VLAN name.
<vlan_name> - Specify the VLAN name.
vlan_id - Specify the RSPAN VLAN by VLAN ID.
<vlanid 1-4094> - Specify the VLAN ID between 1 and 4094.

add - (Optional) Specify to add source ports.
delete - (Optional) Specify to delete source ports.
ports
