Reserve a VLAN (Virtual LAN) with the remote-mirroring keyword in all the intermediate switches for remote mirroring. When you enable mirroring with remote-tag 1000, you need to reserve a VLAN with tag 1000 in all the intermediate switches for remote mirroring. The remote mirroring VLAN in the intermediate switches is used for carrying the mirroring traffic to the destination switch. The ports connecting the source and destination switches are added as tagged in the intermediate switches.
Another way to configure a remote mirroring VLAN is to create a normal VLAN and disable learning on the VLAN. IGMP (Internet Group Management Protocol) snooping must be disabled on that VLAN for you to remotely mirror multicast packets through the switch.
create vlan remote_vlan configure vlan remote_vlan tag 1000 remote-mirroring configure vlan remote_vlan add ports 1,2 tagged
Using the remote-mirroring keyword automatically disables learning and IGMP snooping on the VLAN.
create vlan remote_vlan configure vlan remote_vlan tag 1000 disable learning vlan remote_vlan disable igmp snooping remote_vlan
