The source and destination are configured on different routers for remote mirroring. Note that mirror source and mirror destination parameters must be configured under the same service ID context.
Remote mirroring using MPLS SDP is supported on all 7210 SAS platforms as described in this document, except those operating in access-uplink mode.
The mirror-source commands are used as traffic selection criteria to identify traffic to be mirrored at the source. For example, use the port port-id [lag-id] {[egress] [ingress]} and mac-filter mac-filter-id entry entry-id [entry-id …] commands.
Use the following syntax to configure one or more mirror source parameters.
debug> mirror-source service-id
ip-filter ip-filter-id entry entry-id [entry-id …]
ipv6-filter ip-filter-id entry entry-id [entry-id …]
mac-filter mac-filter-id entry entry-id [entry-id …]
port {port-id|lag lag-id} {[egress][ingress]}
sap sap-id {[ingress]}
no shutdown
The mirror-dest commands are used to specify where the mirrored traffic is to be sent, the forwarding class, and the size of the packet. Use the following syntax to configure mirror destination parameters.
config>mirror#
mirror-dest service-id
[create] [type <mirror-type>][mirror-source-type <mirror-source-type>]
description string
fc fc-name [profile <profile>]
remote-source
far-end ip-address [vc-id vc-id] [ing-svc-label ingress-vc-label|tldp]
sap sap-id create
no shutdown
The following figure shows the mirror destination, which is on ALA-A, configuration for mirror service 1216. This configuration specifies that the mirrored traffic coming from the mirror source (10.10.0.91) is to be directed to SAP /1/58 and states that the service only accepts traffic from far end 10.10.0.92 (ALA-B) with an ingress service label of 5678. When a forwarding class is specified, then all mirrored packets transmitted to the destination SAP or SDP override the default (be) forwarding class.
The following example displays the CLI output showing the configuration of remote mirrored service 1216. The traffic ingressing and egressing port 1/1/60 on 10.10.0.92 (ALA-B) will be mirrored to the destination SAP 1/1/58:0 on ALA-A.
