Interface IP parameters – Layer 2 Switches
Table 147 lists the interface-level IP parameters for Layer 2 Switches.
Configuring IP parameters – Layer 3 Switches
The following sections describe how to configure IP parameters. Some parameters can be
configured globally while others can be configured on individual interfaces. Some parameters can
be configured globally and overridden for individual interfaces.
NOTE
This section describes how to configure IP parameters for Layer 3 Switches. For IP configuration
information for Layer 2 Switches, refer to “Configuring IP parameters – Layer 2 Switches” on
page 862.
Configuring IP addresses
You can configure an IP address on the following types of Layer 3 Switch interfaces:
Ethernet port
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 page 868
DHCP
Client-Based
Auto-Configura
tion
Allows the switch to obtain IP addresses from a DHCP
host automatically, for either a specified (leased) or
infinite period of time.
Enabled page 854
1. Some devices have a factory default, such as 209.157.22.154, used for troubleshooting during installation. For
Layer 3 Switches, the address is on port 1 (or 1/1).

Parameter Description Default See page...
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.
