monitor session destination

This command configures the probe interface for a selected monitor session. This command configures a probe port and a monitored port for monitor session (port monitoring). Use rx to monitor only ingress packets, or use tx to monitor only egress packets. If you do not specify an {rx | tx} option, the destination port monitors both ingress and egress packets.

A VLAN can be configured as the source to a session (all member ports of that VLAN are monitored). Remote port mirroring is configured by adding the RSPAN VLAN ID. At the source switch, the destination is configured as the RSPAN VLAN and at the destination switch, the source is configured as the RSPAN VLAN.

Note

The source and destination cannot be configured as remote on the same device.

The reflector-port is configured at the source switch along with the destination RSPAN VLAN. The reflector-port forwards the mirrored traffic towards the destination switch.

Note

This port must be configured with RSPAN VLAN membership.

Use the destination interface unit/slot/port to specify the interface to receive the monitored traffic.

The port mirroring commands add a mirrored port (source port) to a session identified with session-id. The session-id parameter is an integer value used to identify the session. The maximum number of sessions which can be configured is L7_MIRRORING_MAX_SESSIONS. Option rx is used to monitor only ingress packets. Option tx is used to monitor only egress packets. If no option is specified, both ingress and egress packets, RX and TX, are monitored.

A VLAN can also be configured as the source to a session (all the member ports of that VLAN are monitored).

Note

If an interface participates in some VLAN and is a LAG (Link Aggregation Group) member, this VLAN cannot be assigned as a source VLAN for a Monitor session. At the same time, if an interface participates in some VLAN and this VLAN is assigned as a source VLAN for a Monitor session, the interface can be assigned as a LAG member.

Remote port mirroring is configured by giving the RSPAN VLAN ID. At the source switch the destination is configured as RSPAN VLAN and at the destination switch the source is configured as RSPAN VLAN.

Note

On the intermediate switch: RSPAN VLAN should be created, the ports connected towards Source and Destination switch should have the RSPAN VLAN participation. RSPAN VLAN egress tagging should be enabled on the interface on the intermediate switch connected towards the Destination switch.
