Switch#
show running-config
Step 6
(Optional) Saves your entries in the configuration file. copy running-config startup-config
Example:
Switch# copy running-config startup-config
Step 7
What to Do Next
You must create the RSPAN VLAN in all switches that will participate in RSPAN. If the RSPAN VLAN-ID
is in the normal range (lower than 1005) and VTP is enabled in the network, you can create the RSPAN VLAN
in one switch, and VTP propagates it to the other switches in the VTP domain. For extended-range VLANs
(greater than 1005), you must configure RSPAN VLAN on both source and destination switches and any
intermediate switches.
Use VTP pruning to get an efficient flow of RSPAN traffic, or manually delete the RSPAN VLAN from all
trunks that do not need to carry the RSPAN traffic.
To remove the remote SPAN characteristic from a VLAN and convert it back to a normal VLAN, use the no
remote-span VLAN configuration command.
To remove a source port or VLAN from the SPAN session, use the
no monitor session session_number
source
{
interface interface-id | vlan vlan-id
} global configuration command. To remove the RSPAN VLAN
from the session, use the no monitor session session_number destination remote vlan vlan-id .
Creating an RSPAN Source Session
Follow these steps to create and start an RSPAN source session and to specify the monitored source and the
destination RSPAN VLAN.
