Chapter 32 Configuring SPAN and RSPAN
Configuring FSPAN and FRSPAN
Configuring an FRSPAN Session
Beginning in privileged EXEC mode, follow these steps to start an RSPAN source session, specify the
monitored source and the destination RSPAN VLAN, and configure FRSPAN for the session:
Step 4
monitor session session_number
destination {interface interface-id [, | -]
[encapsulation replicate]}
Specify the SPAN session and the destination port (monitoring port).
For sessi
on_number, specify the session number entered in Step 3.
Note For local SPAN, you must use the same session number for
the source and destination interfaces.
• For interface-id, specify the destination port. The destination
interface must be a physical port; it cannot be an EtherChannel,
and it cannot be a VLAN.
• (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) Enter encapsulation replicate to specify that the
destination interface replicates the source interface
encapsulation method. If not selected, the default is to send
packets in native form (untagged).
Note You can use monitor session session_number destination
command multiple times to configure multiple destination
ports.
Step 5
monitor session session_number filter {ip |
ipv6 | mac} access-group
{access-list-number | name}
Specify the SPAN session, the types of packets to filter, and the ACLs
to use in an FSPAN 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 6
end Return to privileged EXEC mode.
Step 7
show monitor [session session_number]
show running-config
Verify the configuration.
Step 8
copy running-config startup-config (Optional) Save the configuration in the configuration file.
Command Purpose
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
no monitor session {session_number | all |
local | remote}
Remove any existing RSPAN configuration for the session.
For sessi
on_number, the range is 1 to 66.
Specify all to re
move all RSPAN sessions, local to remove all local
sessions, or remote to remove all remote SPAN sessions.
