Use this command to enable a remote mirror using Layer 2 tunneling.
None.
Remote mirroring using Layer 2 tunnels is disabled by default.
Tunnel Interface Configuration command mode.
This command allocates the necessary resources to support mirrored packets. It searches for SMON or policy port mirrors that use the mirror destination port specified in tunnel mode gre l2 (mirrored tunnel). Policy port mirrors are supported on the S- and K-Series. On the S- and K-Series, once the mirrored tunnel is enabled, the specified port is set to loopback mode and Layer 2 traffic will no longer ingress or egress the port, only mirrored traffic from the destination port.
When configuring the L2 tunnel on the remote side, where the remote mirrored port destination resides, do not enable the L2 tunnel using this command.
Use the “no” option for this command to disable the Layer 2 mirrored tunnel.
This S- and K-Series example shows how to enable the L2 mirrored tunnel for the mirror-destination port ge.1.8:
System(rw)->configure System(rw-config)->interface tunnel 5 System(rw-config-intf-tun.0.5)->tunnel destination 99.99.99.1 System(rw-config-intf-tun.0.5)->tunnel mode gre l2 ge.1.8 System(rw-config-intf-tun.0.5)->tunnel source 88.88.88.1 System(rw-config-intf-tun.0.5)->tunnel mirror enable System(rw-config-intf-tun.0.5)->no shutdown System(rw-config-intf-tun.0.5)->exit System(rw-config)->
This 7100-Series example shows how to enable the L2 mirrored tunnel for the mirror-destination port ge.1.8:
System(rw)->configure System(rw-config)->interface tunnel 5 System(rw-config-intf-tun.0.5)->tunnel destination 99.99.99.1 System(rw-config-intf-tun.0.5)->tunnel mode gre l2 tbp.0.1 System(rw-config-intf-tun.0.5)->tunnel source 88.88.88.1 System(rw-config-intf-tun.0.5)->tunnel mirror enable System(rw-config-intf-tun.0.5)->no shutdown System(rw-config-intf-tun.0.5)->exit System(rw-config)->
