Bridging
• IEEE 802.1D transparent bridging
•
Up to 4096 MAC entries address table
•
Port-based VLAN (Virtual Local Area Network)
IEEE 802.1Q Tagged VLAN
Your ADSL line card uses the IEEE 802.1Q Tagged VLAN (Virtual Local Area Network), which allows your
device to deliver tagged/untagged frames to and from its ports. The line card supports up to 255 VLANs and the
maximum VLAN ID 4094.
Fast Mode
The fast mode makes use of the “tag” subset of the IEEE 802.1Q standard to identify the source port of a frame
and speed traffic through a service gateway.
MAC (Media Access Control) Filtering
The line card can filter incoming frames based on MAC (Media Access Control) address(es) that you specify. You
may enable/disable specific ports. You may specify up to five MAC addresses per port.
Secured Host
Allow up to ten remote hosts to access the line card via IP addresses you specify.
