PurposeCommand or Action
Enters the global configuration mode.configure terminal
Example:
Switch# configure terminal
Step 2
Removes any existing SPAN configuration for the session.
no monitor session {session_number | all
| local | remote}
Step 3
•
For session_number, the range is 1 to 66.
Example:
Switch(config)# no monitor session
all
• all—Removes all SPAN sessions.
• local—Removes all local sessions.
• remote—Removes all remote SPAN sessions.
Specifies the SPAN session and the source port (monitored port).
monitor session session_number source
{interface interface-id | vlan vlan-id} [, |
-] [both | rx | tx]
Step 4
•
For session_number, the range is 1 to 66.
Example:
Switch(config)# monitor session 1
•
For interface-id, specify the source port to monitor. Valid interfaces
include physical interfaces and port-channel logical interfaces
(port-channel port-channel-number). Valid port-channel numbers are
1 to 48.
source interface
gigabitethernet1/0/1
•
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.
Note
•
(Optional) [, | -] Specifies a series or range of interfaces. Enter a space
before and after the comma; enter a space before and after the hyphen.
• (Optional) both | rx | tx—Specifies the direction of traffic to monitor.
If you do not specify a traffic direction, the source interface sends both
sent and received traffic.
◦ both—Monitors both received and sent traffic.
◦ rx—Monitors received traffic.
◦ tx—Monitors sent traffic.
You can use the monitor session session_number source
command multiple times to configure multiple source
ports.
Note
Specifies the SPAN session and the destination port (monitoring port).
monitor session session_number
destination {interface interface-id [, | -]
[encapsulation replicate]}
Step 5
For local SPAN, you must use the same session number for the source
and destination interfaces.
