Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 37)

IP global parameters - Layer 2 switches (Continued) TABLE 4
Parameter Description Default
Time to Live (TTL) The maximum number of routers (hops) through which a packet
can pass before being discarded. Each router decreases a packet
TTL by 1 before forwarding the packet. If decreasing the TTL
causes the TTL to be 0, the router drops the packet instead of
forwarding it. 64 hops
Domain name for
Domain Name
Server (DNS)
resolver A domain name (example: brocade.router.com) you can use in
place of an IP address for certain operations such as IP pings,
trace routes, and Telnet management connections to the router. None configured
DNS default
gateway addresses A list of gateways attached to the router through which clients
attached to the router can reach DNSs. None configured
Source interface The IP address the Layer 2 switch uses as the source address for
Telnet, RADIUS, or TACACS/TACACS+ packets originated by the
router. The Layer 2 switch uses its management IP address as the
source address for these packets. The management IP
address of the Layer 2
switch.
NOTE
This parameter is not
configurable on Layer 2
switches.
DHCP gateway
stamp The device can assist DHCP/BootP Discovery packets from one
subnet to reach DHCP/BootP servers on a different subnet by
placing the IP address of the router interface that forwards the
packet in the packet Gateway field.
You can specify up to 32 gateway lists. A gateway list contains up
to eight gateway IP addresses. You activate DHCP assistance by
associating a gateway list with a port.
When you configure multiple IP addresses in a gateway list, the
Layer 2 switch inserts the addresses into the DHCP Discovery
packets in a round robin fashion.
None configured
DHCP Client-
Based Auto-
Configuration Allows the switch to obtain IP addresses from a DHCP host
automatically, for either a specified (leased) or infinite period of
time. Enabled

Interface IP parameters - Layer 2 switches TABLE 5
Parameter Description Default
DHCP gateway stamp You can configure a list of DHCP stamp addresses for a port. When the
port receives a DHCP/BootP Discovery packet from a client, the port
places the IP addresses in the gateway list into the packet Gateway field.
None configured
