Configuring IP Addressing

IP Configuration

 

Removing or Replacing IP Addresses in a Multinetted VLAN. To

 

remove an IP address from a multinetted VLAN, use the no form of the IP

 

address command shown on page 8-8.Generally, to replace one IP address

 

with another, you should first remove the address you want to replace, and

 

then enter the new address.

 

Configure the Optional Default Gateway. Using the Global configura-

 

tion level, you can manually assign one default gateway to the switch. (The

 

switch does not allow IP addressing received from a DHCP or Bootp server

 

to replace a manually configured default gateway.)

 

Syntax: ip default-gateway < ip-address >

 

For example:

 

ProCurve(config)# ip default-gateway 10.28.227.115

 

 

Note

The switch uses the IP default gateway only while operating as a Layer 2

 

device. While routing is enabled on the switch, the IP default gateway is not

 

used. Thus, to avoid loss of Telnet access to off-subnet management stations,

 

you should use the ip route command to configure a static (default) route

 

before enabling routing. For more information, refer to the chapter titled “IP

 

Routing Features” in the Multicast and Routing Guide for your switch.

 

Configure Time-To-Live (TTL). The maximum number of routers (hops)

 

 

through which a packet can pass before being discarded. (The default is 64.)

 

Each router decreases a packet’s TTL by 1 before forwarding the packet. If a

 

router decreases the TTL to 0, the router drops the packet instead of forward-

 

ing it.

 

Syntax: ip ttl <number-of-hops>

 

ProCurve(config)# ip ttl 60

 

In the CLI, you can execute this command only from the global configuration

 

level. The TTL default is 64, and the range is 2 - 255.

 

Web: Configuring IP Addressing

 

You can use the web browser interface to access IP addressing only if the

 

switch already has an IP address that is reachable through your network.
