Ip Packet Flow Through A Layer 3 Switch - Foundry Networks Switch and Router Installation And Configuration Manual

The number of IP addresses you can configure on an individual interface depends on the Layer 3 Switch model.
To display the maximum number of IP addresses and other system parameters you can configure on a Layer 3
Switch, see "Displaying and Modifying System Parameter Default Settings" on page 10-70.
You can use any of the IP addresses you configure on the Layer 3 Switch for Telnet, Web management, or SNMP
access.
Layer 2 Switches
You can configure an IP address on a Foundry Layer 2 Switch for management access to the Layer 2 Switch. An
IP address is required for Telnet access, Web management access, and SNMP access.
You also can specify the default gateway for forwarding traffic to other sub-nets.
