This section provides the following configuration examples:

• SPAN Source Configuration: Example, page 84

• SPAN Destination Configuration: Example, page 84

• Removing Sources or Destinations from a SPAN Session: Example, page 84

SPAN Source Configuration: Example

The following example shows SPAN session 1 being configured to monitor bidirectional traffic from

source interface Gigabit Ethernet 0/1/1:

Router(config)#monitor session 1 source interface gigabitethernet 0/1/1

SPAN Destination Configuration: Example

The following example shows interface Gigabit Ethernet 0/1/7 being configured as the destination for

SPAN session 1:

Router(config)#monitor session 1 destination interface gigabitethernet 0/1/7

Removing Sources or Destinations from a SPAN Session: Example

This following example shows interface Gigabit Ethernet 0/1/2 being removed as a SPAN source for

SPAN session 1:

Router(config)#no monitor session 1 source interface gigabitethernet 0/1/2

IGMP Snooping: Example

The following example shows the output from configuring IGMP snooping:

Router#show mac-address-table multicast igmp-snooping
