Configuring IP Addressing

IP Configuration

Configure the Optional Default Gateway. Using the Global configura­

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

 

Syntax:

ip default-gateway <ip-address>

 

For example:

 

HPswitch(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. Refer to chapter 16, “IP Routing Features”, for more

 

information.

 

Configure Time-To-Live (TTL). Use this command at the Global config

 

 

prompt to set the time that a packet outbound from the switch can exist on

 

the network. The default setting is 64 seconds.

 

Syntax:

ip ttl <number-of-seconds>

 

HPswitch(config)# ip ttl 60

 

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

 

level. The TTL range is 2 - 255 seconds.

 

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].

How IP Addressing Affects Switch Operation

Without an IP address and subnet mask compatible with your network, the switch can be managed only through a direct terminal device connection to the Console RS-232 port. You can use direct-connect console access to take advantage of features that do not depend on IP addressing. However, to realize the full performance capabilities HP proactive networking offers through the
