PurposeCommand or Action
Removes any existing SPAN configuration for the session.
no monitor session {session_number |
all | local | remote}
Step 2
•
For session_number, the range is 1 to 66.
Example:
Switch(config)# no monitor session
2
• 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 3
•
For session_number, the range is 1 to 66.
Example:
Switch(config)# monitor session 2
•
For interface-id, specify the source port or the source VLAN to monitor.
•
For source interface-id, specify the source port to monitor. Only physical
interfaces are valid.
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 SPAN monitors both sent and
received traffic.
◦ both—Monitors both sent and received traffic. This is the default.
◦ 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 4
•
For session_number, specify the session number entered in Step 3.
Example:
Switch(config)# monitor session 2
•
For destination, specify the following parameters:
◦
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.
destination interface
gigabitethernet1/0/2 encapsulation
replicate
◦
(Optional) [, | -] Specifies a series or range of interfaces. Enter a space
before and after the comma; enter a space before and after the hyphen.
