Chapter 66 Configuring SPAN and RSPAN
Configuring RSPAN
This example shows how to remove port 1 as an RSPAN source for RSPAN session 1:
Switch#
configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
no monitor session 1 source interface gigabitEthernet1/1
Switch(config)#
end
This example shows how to disable received traffic monitoring on port 1, which was configured for
bidirectional monitoring:
Switch(config)#
no monitor session 1 source interface gigabitEthernet1/1 rx
The monitoring of traffic received on port 1 is disabled, but traffic transmitted from this port continues
to be monitored.
Specifying VLANs to Monitor
VLAN monitoring is similar to port monitoring. To specify VLANs to monitor, perform this task:
Command
Purpose
Step 1
Switch#
configure terminal
Enters global configuration mode.
Step 2
Switch(config)# [
no
]
monitor session
{
session_number
} {
source
{
interface
interface_list
| {
vlan
vlan_IDs
|
cpu
[
queue
queue_ids
]} [
rx
|
tx
|
both
]
Specifies the characteristics of the RSPAN source port (monitored
port) to remove.
For
session_number
, specifies the session number identified with
this RSPAN session (1 through 6).
For
interface-list
, specifies the source port to no longer monitor.
Valid interfaces include physical interfaces and port-channel
logical interfaces (
port-channel
port-channel-number
).
For
vlan_IDs
, specifies the source vlan or vlans to monitor. Valid
VLANs are in the range from 1 to 4094.
For
queue_ids
, specifies either a set of CPU queue numerical
identifiers from 1 to 32, or a named queue.
(Optional) [
,
|
-
] Specifies a series or range of interfaces. Enter a
space after the comma; enter a space before and after the hyphen.
(Optional) Specifies the direction of traffic to monitor. If you do
not specify a traffic direction, the source interface sends both
transmitted (Tx) and received (Rx) traffic. Only received traffic can
be monitored on additional source ports.
•
Rx
—Monitor received traffic.
•
Tx
—Monitor transmitted traffic.
•
both
—Monitor both received and transmitted traffic
(bidirectional).
Step 3
Switch(config)#
end
Returns to privileged EXEC mode.
Step 4
Switch#
show monitor
[
session
session_number
]
Verifies your entries.
Step 5
Switch#
copy running-config
startup-config
(Optional) Saves your entries in the configuration file.
