Configuring IP Addressing

 

 

IP Configuration

 

 

NoteThe 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.

 

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 capabilities ProCurve proactive networking offers through the switch, configure the switch with an IP address and subnet mask compatible with your network. The following table lists the general features available with and without a network-compatible IP address configured.
