![]() The following example shows valid IP address configurations on two loopback interfaces. If a poorly programmed host actually sends a ping from the loopback address on the wire, the receiving host, if it doesnt simply discard the packet, is only going to respond to itself. Up to thirty-two IP addresses are supported on a loopback interface. A loopback address (127/8) isnt routeable. You can configure multiple IP addresses on a loopback interface ( lo0 to lo7). In the same way, if you configure a loopback interface ( lo1) with IP address 172.16.101.8, you cannot configure another loopback interface ( lo2) with IP address 172.16.101.8. This means that the address cannot be used by a VLAN interface or another loopback interface.įor example, if you configure a VLAN with IP address 172.16.100.8/24, you cannot configure a loopback interface with IP address 172.16.100.8. The maximum number of IP addresses supported on a switch is 2048, which includes all IP addresses configured for both VLANs and loopback interfaces (except for the default loopback IP address 127.0.0.1).Įach IP address that you configure on a loopback interface must be unique in the switch. ![]() The local IP address is on one of your other network interfaces. The two are on different 'interfaces' - the lookback address is on the loopback interface which should be present always (unless you've done something really freaky with your config). Loopback interfaces share the same IP address space with VLAN configurations. 3 Answers Sorted by: 2 When everything is working correctly, they should have the same effect. ![]() You can configure a loopback interface only from the CLI you cannot configure a loopback interface from the WebAgent or Menu interface. ![]()
