Monitoring Specific Source Vlans On A Source Trunk Port; Configuring Local Span And Rspan Destinations - Cisco 7609 Configuration Manual

Configuring Local SPAN and RSPAN
This example shows how to configure session 1 to monitor bidirectional traffic from Fast Ethernet
port 5/1:
Router(config)# monitor session 1 source interface fastethernet 5/1

Monitoring Specific Source VLANs on a Source Trunk Port

To monitor specific VLANs when the local or RSPAN source is a trunk port, perform this task:
Command
Router(config)# monitor session session_number filter
{vlan_ID} [, | -]
Router(config)# no monitor session session_number
filter {vlan_ID}
This example shows how to monitor VLANs 1 through 5 and VLAN 9 when the source is a trunk port:
Router(config)# monitor session 2 filter vlan 1 - 5 , 9

Configuring Local SPAN and RSPAN Destinations

These sections describe how to configure local SPAN and RSPAN destinations:

Configuring a Destination Port as an Unconditional Trunk
To tag the monitored traffic with Release 12.1(13)E and later releases, configure the destination port as
a trunk.
To configure the destination port as a trunk, perform this task:
Command
Step 1
Router(config)# interface type
Step 2
Router(config-if)# switchport
Step 3
Router(config-if)# switchport trunk encapsulation
{isl | dot1q}
Step 4
Router(config-if)# switchport mode trunk
Step 5
Router(config-if)# switchport nonegotiate
1. type = ethernet, fastethernet, gigabitethernet, or tengigabitethernet

Purpose
Monitors specific VLANs when the source is a trunk port.
Clears trunk source configuration.
Purpose
Selects the LAN port to configure.
Configures the LAN port for Layer 2 switching (required
only if the LAN port is not already configured for Layer
2 switching).
Configures the encapsulation, which configures the Layer
2 switching port as either an ISL or 802.1Q trunk.
Configures the port to trunk unconditionally.
Configures the trunk not to use DTP.
