Configuring Ip Filtering - 3Com 4500 PWR 26-Port Configuration Manual

If you configure a remote ID sub-option in both system view and on a port, the remote ID
sub-option configured on the port applies when the port receives a packet, and the globa
ID applies to other interfaces that have no remote ID sub-option configured.
If you have configured a remote ID wit
without the argument in Ethernet port view, the former remote ID applies to the DHCP messages
from the specified VLAN, while the latter one applies to DHCP messages from other VLANs.
In a port aggregation group, you can use this command to configure
respectively. When Option 82 is added, however, the remote ID is subject to the one configured on
the primary port.
The remote ID configured on a port will neither be synchronized in the case of port aggregation nor
support XRN.
