IP interface parameters - Layer 3 switches
TABLE 3 IP interface parameters - Layer 3 switches
Parameter Description Default
IP state The Internet Protocol, version 4 Enabled
NOTE
You cannot disable IP.
IP address A Layer 3 network interface address
NOTE
Layer 2 switches have a single IP
address used for management
access to the entire device. Layer 3
switches have separate IP addresses
on individual interfaces.
None congured
NOTE
Some devices have a factory default,
such as 10.157.22.154, used for
troubleshooting during installation.
For Layer 3 switches, the address is
on unit 1/slot 1/ port 1 (or 1/1/1).
Encapsulation type The format of the packets in which the router
encapsulates IP datagrams. The encapsulation
format can be one of the following:
• Ethernet II
• SNAP
Ethernet II
Maximum Transmission Unit (MTU) The maximum length (number of bytes) of an
encapsulated IP datagram the router can
forward.
1500 for Ethernet II encapsulated packets
1492 for SNAP encapsulated packets
Delay L3 notications When all ports in the VLAN go into the non-
forwarding state, the device waits for the
congured time before notifying the Layer 3
protocols of the VE down event.
NOTE
Available on the VE interface only.
Delay time is not congured
ARP age Locally overrides the global setting. Ten minutes
Directed broadcast forwarding Locally overrides the global setting. Disabled
ICMP Router Discovery Protocol (IRDP) Locally overrides the global IRDP settings. Disabled
DHCP gateway stamp The router can assist DHCP/BootP Discovery
packets from one subnet to reach DHCP/BootP
servers on a dierent subnet by placing the IP
address of the router interface that receives the
request in the request packet Gateway eld.
You can override the default and specify the IP
address to use for the Gateway eld in the
packets.
NOTE
UDP broadcast forwarding for client
DHCP/BootP requests (bootps)
must be enabled (this is enabled by
default) and you must congure an
IP helper address (the server IP
address or a directed broadcast to
the server subnet) on the port
connected to the client.
The lowest-numbered IP address on the
interface that receives the request
