Purpose
Specify the RSPAN session and the source port (monitored port).
For session_number, the range is 1 to 66.
Enter a source port or source VLAN for the RSPAN session:
For source interface-id, specify the source port to monitor. Only
•
physical interfaces are valid.
For vlan-id, specify the source VLAN to monitor. The range is 1
•
to 4094 (excluding the RSPAN VLAN).
A single session can include multiple sources (ports or VLANs),
defined in a series of commands, but you cannot combine source
ports and source VLANs in one session.
(Optional) [, | -] Specify a series or range of interfaces. Enter a
•
space before and after the comma; enter a space before and after
the hyphen.
(Optional) Specify the direction of traffic to monitor. If you do
•
not specify a traffic direction, the source interface sends both
sent and received traffic.
both—Monitor both received and sent traffic.
•
rx—Monitor received traffic.
•
tx—Monitor sent traffic.
•
Specify the RSPAN session and the destination RSPAN VLAN.
For session_number, enter the number defined in Step 3.
•
For vlan-id, specify the source RSPAN VLAN to monitor.
•
Enter the VLAN sub-mode. For vlan-id, specify the source RSPAN
VLAN to monitor.
Indicate that the VLAN you specified in Step 5 is part of the RSPAN
VLAN.
Return to global configuration mode.
Specify the RSPAN session, the types of packets to filter, and the
ACLs to use in an FRSPAN session.
For session_number, specify the session number entered in
•
Step 3.
For access-list-number, specify the ACL number that you want
•
to use to filter traffic.
For name, specify the ACL name that you want to use to filter
•
traffic.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save the configuration in the configuration file.
