What address can you ping to get a loop back?
127.0.0.1
In a TCP/IP network, the loopback IP address is 127.0. 0.1, and pinging this address will always return a reply unless the firewall prevents it.
What is the loop back IP address?
A loopback address is a special IP address, 127.0. 0.1, reserved by InterNIC for use in testing network cards. This IP address corresponds to the software loopback interface of the network card, which does not have hardware associated with it, and does not require a physical connection to a network.
What is the loopback interface?
A loopback interface is a virtual interface that is always up and reachable as long as at least one of the IP interfaces on the switch is operational. As a result, a loopback interface is useful for debugging tasks since its IP address can always be pinged if any other switch interface is up.
How do you ping a loop?
Continuous ping in Windows 7, 8, and 10 Step 1: Open the Windows command prompt. One way of doing this is by entering the key combination Windows + R and enter the command CMD. Step 2: Enter the command line ping with the -t option and any address and confirm by clicking [Enter].
Can You Ping the loopback interface on switch 1?
Currently, I am able to ping the loopback interface on switch 1 but not on switch 2 from any computer in the 2 VLANS i created. i have enable IP routing on both switches. I can ping the computers both vlans and the vlan ip addresses. I can also ping the switch 2 loopback interface from switch 2 but not from anywhere else.
Why is loopback not responding to my ARP request?
But this I don’t think I understand. If the loopback IP address in on the same subnet as that assigned to the VLAN on the port coming into the switch, wouldn’t it just switch the traffic over to the loopback interface? Why won’t it answer the ARP request?
Can You Ping the loopback on a catalyst 2960?
04-25-2014 02:36 PM 04-25-2014 02:36 PM I don’t really understand why the answer to the question worked before, but I have an almost identical problem. Here’s the old discussion: I can’t ping the loopback on a Catalyst 2960. I have a VLAN 33 on a 10.0.33.0 subnet. This is being routed over an 881 using an SVI (with 10.0.33.1) on the back side.
Why do Loopback interfaces not make much sense?
This is the reason loopback interfaces do not make much sense on Layer2 switches and on limited-feature Layer3 switches. These switches are incapable of routing whatsoever, or they have no way of advertising their loopback interfaces in a routing protocol. This makes the loopback interfaces effectively unreachable.
