Configuring IP Addressing, Interface Access, and System Information
IP Configuration
Configuring IP Addressing,
Interface Access, and
Configure an IP Address and Subnet Mask. The following command
includes both the IP address and the subnet mask. You must either include the
ID of the VLAN for which you are configuring IP addressing or go to the
context configuration level for that VLAN. (If you are not using VLANs on the
switch—that is, if the only VLAN is the default VLAN—then the VLAN ID is
always “1”.)
Note The default IP address setting for the DEFAULT_VLAN is DHCP/Bootp. On
additional VLANs you create, the default IP address setting is Disabled.
Syntax: vlan <vlan-id> ip address <ip-address/mask-length>
or
vlan <vlan-id> ip address <ip-address> <mask-bits>
or
vlan <vlan-id> ip address dhcp-bootp
This example configures IP addressing on the default VLAN with the subnet
mask specified in mask bits.
HP2512(config)# vlan 1 ip address 10.28.227.103/255.255.255.0
This example configures the same IP addressing as the preceding example,
but specifies the subnet mask by mask length.
HP2512(config)# vlan 1 ip address 10.28.227.103/24
Configure the Optional Default Gateway. You can assign one default
gateway to the switch.
Syntax: ip default-gateway <ip-address>
For example:
HP2512(config)# ip default-gateway 11.28.227.115
You can execute this command only from the global configuration level.
Configure Time-To-Live (TTL). This command sets 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>
HP2512(config)# ip ttl 60
