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 configuration 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 forwarding it. Syntax: ip ttl 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]. 8-10
