VLAN to act like a HUB ( no mac learning )

XoS, I wish to have a vlan act like hub in the MAC learning sense, I just wish it to flood all traffic to all ports in that vlan. this is because this vlan is reciving some mirrored traffic from a another vendors equipment and I have a remote packet capture device. the trunk links are shared so I cannot change the learning on a ports basis. really I need to turn of mac learning for a vlan.
Thanks in advance,
Simon

There is option 'remote-mirroring' when you configure vlan and it does exactly what you need.

A little belated on my part, but thanks for your answer.

from concepts guide:
Configuring the Intermediate Switch
Reserve a VLAN 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 snooping must be disabled on that VLAN for you to remotely mirror multicast packets through the switch.

Hey thanks for that response, I often wondered if this remote mirroring is simply a vlan with learning turned off I bet it is.
Juniper as a "no-mac-learning" command, this may be the equivalent
