Configuring IP Addressing
IP Configuration
Note
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
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.
