Step 3
monitor session session_number source
{ interface interface-id | vlan vlan-id } [, | -]
[ both | rx | tx ]
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.
Step 4
monitor session session_number
destination remote vlan vlan-id
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.
Step 5 vlan vlan-id Enter the VLAN sub-mode. For vlan-id , specify the source RSPAN
VLAN to monitor.
Step 6 remote-span Indicate that the VLAN you specified in Step 5 is part of the RSPAN
VLAN.
Step 7 exit Return to global configuration mode.
Step 8
monitor session session_number filter { ip |
ipv6 | mac } access-group
{ access-list-number | name }
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.
Step 9 end Return to privileged EXEC mode.
Step 10
show monitor [ session session_number ]
show running-config
