SPAN and RSPAN Configuration Examples

Example: Configuring Local SPAN

This example shows how to set up SPAN session 1 for monitoring source port traffic to a destination port. First, any existing SPAN configuration for session 1 is deleted, and then bidirectional traffic is mirrored from source Gigabit Ethernet port 1 to destination Gigabit Ethernet port 2, retaining the encapsulation method.

Switch(config)# no monitor session 1

Switch(config)# monitor session 1 source interface gigabitethernet1/0/1 Switch(config)# monitor session 1 destination interface gigabitethernet1/0/2 encapsulation replicate

Switch(config)# end

This example shows how to remove port 1 as a SPAN source for SPAN session 1:

Switch(config)# no monitor session 1 source interface gigabitethernet1/0/1

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 gigabitethernet1/0/1 rx

The monitoring of traffic received on port 1 is disabled, but traffic sent from this port continues to be monitored.

This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on all ports belonging to VLANs 1 through 3, and send it to destination Gigabit Ethernet port 2. The configuration is then modified to also monitor all traffic on all ports belonging to VLAN 10.

Switch(config)# no monitor session 2

Switch(config)# monitor session 2 source vlan 1 - 3 rx

Switch(config)# monitor session 2 destination interface gigabitethernet1/0/2

Switch(config)# monitor session 2 source vlan 10

Switch(config)# end

This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor received traffic on Gigabit Ethernet source port 1, and send it to destination Gigabit Ethernet port 2 with the same egress encapsulation type as the source port, and to enable ingress forwarding with IEEE

802.1Q encapsulation and VLAN 6 as the default ingress VLAN:

Switch(config)# no monitor session 2

Switch(config)# monitor session 2 source gigabitethernet1/0/1 rx

Switch(config)# monitor session 2 destination interface gigabitethernet1/0/2 encapsulation replicate ingress dot1q vlan 6

Switch(config)# end

This example shows how to remove any existing configuration on SPAN session 2, configure SPAN session 2 to monitor traffic received on Gigabit Ethernet trunk port 2, and send traffic for only VLANs 1 through 5 and VLAN 9 to destination Gigabit Ethernet port 1:

Switch(config)# no monitor session 2

Switch(config)# monitor session 2 source interface gigabitethernet1/0/2 rx

Switch(config)# monitor session 2 filter vlan 1 - 5 , 9
