Menu: configuring IP address, Gateway, and Time-To-Live (TTL)
Do one of the following:
• To manually enter an IP address, subnet mask, set the IP Config parameter to Manual and
then manually enter the IP address and subnet mask values you want for the switch.
• To use DHCP or Bootp, use the menu interface to ensure that the IP Config parameter is
set to DHCP/Bootp, then see“DHCP/Bootp operation” (page 109).
To configure IP addressing.
1. From the Main Menu, select:
2. Switch Configuration...
5. IP Configuration
NOTE: If multiple VLANs are configured, a screen showing all VLANs appears instead of
the following screen.
The Menu interface displays the IP address for any VLAN. If you use the CLI to configure the
IP address on a VLAN, use the CLI show ip command to list them.
See figure below:
2. Press [E] (for Edit).
3. If the switch needs to access a router, for example, to reach off-subnet destinations, select the
Default Gateway field and enter the IP address of the gateway router.
4. If you need to change the packet Time-To-Live (TTL) setting, select Default TTL and type in a
value between 2 and 255.
5. To configure IP addressing, select IP Config and do one of the following:
• If you want to have the switch retrieve its IP configuration from a DHCP or Bootp server,
at the IP Config field, keep the value as DHCP/ Bootp and go to step 8.
• If you want to manually configure the IP information, use the Space bar to select Manual
and use the [Tab] key to move to the other IP configuration fields.
6. Select the IP Address field and enter the IP address for the switch.
7. Select the Subnet Mask field and enter the subnet mask for the IP address.
8. Press [Enter], then [S] (for Save).
CLI: Configuring IP Address, Gateway, and Time-To-Live (TTL)
Viewing the current IP configuration.
Syntax:
show ip
This command displays the IP addressing for each VLAN configured in the switch.
If only the DEFAULT_VLAN exists, then its IP configuration applies to all ports in the
switch. Where multiple VLANs are configured, the IP addressing is listed per VLAN.
The display includes switch-wide packet time-to-live, and (if configured) the switch’s
default gateway and Timep configuration.
(You can also use the show management command to display the IP addressing and time server
IP addressing configured on the switch. See the Management and Configuration Guide for your
switch.)
For example, in the factory-default configuration (no IP addressing assigned), the switch’s IP
addressing appears as:
