30 Introduction
IP Interface Configuration
IP interface configuration includes the ability to configure the bandwidth, Destination Unreachable
messages, and ICMP Redirect messages.
IP Helper
Provides the ability to relay various protocols to servers on a different subnet.
VRRP Route Interface Tracking
Extends the capability of the Virtual Router Redundancy Protocol (VRRP) to allow tracking of specific
route/interface IP state within the router that can alter the priority level of a virtual router for a VRRP
group.
The exception to this is, if that VRRP group is the IP address owner, its priority is fixed at 255 and can
not be reduced through tracking process.
MAC Address Supported Features
MAC Address Support
The switch supports up to 32K Media Access Control (MAC) addresses and reserves two MAC addresses
for system use.
Self-Learning MAC Addresses
The switch enables MAC addresses to be automatically learned from incoming packets.
Automatic Aging for MAC Addresses
MAC addresses that have not seen any traffic for a given period are aged out, which prevents the bridging
table from overflowing.
For information about configuring the MAC Address age-out period, see "Dynamic Address Table."
Static MAC Entries
User-defined MAC entries are stored in the Bridging Table with the self-learned addresses.
For information about configuring the static MAC addresses, see "Static Address Table."
VLAN-Aware MAC-based Switching
Packets arriving from an unknown source address are sent to the CPU and added to the Hardware Table.
Future packets addressed to or from this address are more efficiently forwarded.
