RELEASE NOTES
Linksys One Ready Communications Solution
1 February 2007
Auto-negotiation advertisement is also supported. Port advertisement allows the system administrator to
configure the port speeds advertised.
Manual Port Control and Identification
While port settings can be derived automatically, as described above, many settings can be set by the
user manually.
MAC Address Supported Features
MAC Address Capacity Support
This device supports up to 8K MAC addresses. It reserves specific MAC addresses for system use.
Static MAC Entries
MAC entries can be manually entered in the Bridging Table, as an alternative to learning them from
incoming frames. These user-defined entries are not subject to aging and are preserved across resets and
reboots.
Automatic Aging for MAC Addresses
MAC addresses from which no traffic is received for a given period are aged out. This prevents the
Bridging Table from overflowing.
VLAN-aware MAC-based Switching
The device always performs VLAN-aware bridging. Classic bridging (IEEE802.1D) is not performed,
where frames are forwarded based only on their destination MAC address. However, a similar
functionality may be configured for untagged frames. Frames addressed to a destination MAC address
that are not associated with any port are flooded to all ports of the relevant VLAN.
MAC/IP Address to Port View
Displays the MAC addresses and IP addresses that are associated with a given port. For each port, it is
possible to display the MAC addresses and IP addresses that are associated with that port. The
information is based on information available in the ARP table, but is presented differently.
Layer 2 Features
IGMP Snooping
IGMP Snooping examines IGMP frame contents when they are forwarded by the device from work
stations to an upstream Multicast router. From the frame, the device identifies work stations configured
for Multicast sessions and identifies which Multicast routers are sending Multicast frames.
Port Mirroring
Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing
packets from a monitored port to a monitoring port. Users specify which target port receives copies of all
traffic passing through a specified source port.
