monitor session Chapter 2 Cisco Catalyst Blade Switch 3020 for HP Cisco IOS Commands monitor session Use the monitor session global configuration command to start a new Switched Port Analyzer (SPAN) session or Remote SPAN (RSPAN) source or destination session, to enable ingress traffic on the destination port for a network security device (such as a Cisco IDS Sensor Appliance), to add or delete interfaces or VLANs to or from an existing SPAN or RSPAN session, and to limit (filter) SPAN source traffic to specific VLANs. Use the no form of this command to remove the SPAN or RSPAN session or to remove source or destination interfaces or filters from the SPAN or RSPAN session. For destination interfaces, the encapsulation options are ignored with the no form of the command. monitor session session_number destination {interface interface-id [, | -] [encapsulation replicate] [ingress {dot1q vlan vlan-id | isl | untagged vlan vlan-id | vlan vlan-id}]} | {remote vlan vlan-id} monitor session session_number filter vlan vlan-id [, | -] monitor session session_number source {interface interface-id [, | -] [both | rx | tx]} | {vlan vlan-id [, | -] [both | rx | tx]}| {remote vlan vlan-id} no monitor session {session_number | all | local | remote} no monitor session session_number destination {interface interface-id [, | -] [encapsulation replicate] [ingress {dot1q vlan vlan-id | isl | untagged vlan vlan-id | vlan vlan-id}]} | {remote vlan vlan-id} no monitor session session_number filter vlan vlan-id [, | -] no monitor session session_number source {interface interface-id [, | -] [both | rx | tx]} | {vlan vlan-id [, | -] [both | rx | tx]} | {remote vlan vlan-id} Syntax Description session_number destination interface interface-id encapsulation replicate Specify the session number identified with the SPAN or RSPAN session. The range is 1 to 66. Specify the SPAN or RSPAN destination. A destination must be a physical port. Specify the destination or source interface for a SPAN or RSPAN session. Valid interfaces are physical ports (including type and port number). For source interface, port channel is also a valid interface type, and the valid range is 1 to 48. (Optional) Specify that the destination interface replicates the source interface encapsulation method. If not selected, the default is to send packets in native form (untagged). ingress dot1q vlan vlan-id isl These keywords are valid only for local SPAN. For RSPAN, the RSPAN VLAN ID overwrites the original VLAN ID; therefore, packets are always sent untagged. (Optional) Enable ingress traffic forwarding. Accept incoming packets with IEEE 802.1Q encapsulation with the specified VLAN as the default VLAN. Specify ingress forwarding using ISL encapsulation. 2-216 Cisco Catalyst Blade Switch 3020 for HP Command Reference OL-8916-01
