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

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.

1. Click on the Configuration tab.

2. Click on

[IP Configuration].

3. If you need further information on using the web browser interface, click

[?] to access the web-based help available for the switch.
