Cisco port status command

It can be very useful at troubleshooting connectivity issues and physical port issues, check the status of physical ports, watch how much traffic is passing through the interface, which IP address is assigned to the interface for Layer3 interfaces etc, cisco port status command. This command works on both Cisco Switches cisco port status command Cisco Routers and has the same functionality on both types of devices. On a Layer 2 switch we can check the status and various other counters and metrics for each physical ethernet interface or for every interface on the device.

Just tested this Junos Automation slax op script and it works well just missing the description field you may be used to in Cisco. A customer asked for some help on this the other day. They're very used to seeing the interface description a la Cisco and wondered if it was possible to adjust the slax script mentioned above to fit. When I run it all I get are the headers, no data. The Script use the Command "show ethernet-switching interfaces", who doesnt exists on the EX There only exist a Command "show ethernet-switching interface" without "s" , and the output is tottaly different. This also not exists on EX I just checked on an EX and yes the command structure for ELS is indeed "interface" versus "interfaces". I think I have edit the script to now work with ELS code. In meatime will look into command structure change.

The most important data you need to take into consideration are the following:. On a Layer 3 router, the show interface command is equally important to obtain crucial information about each interface for various purposes. Switch Switch traceroute mac ip 1.

Optional Number of the module. If you do not specify a number, the ports on all modules are shown. Optional Number of the port on the module. If you do not specify a number, all the ports on the module are shown. Status of the port connected, notconnect, connecting, standby, faulty, inactive, shutdown, disabled, or monitor.

In order to check to see how long the port is in Up or Down status, use the show interfaces [interface id] command. This shows the last time a port sent or received traffic. Likewise, the Last input never, output never, output hang never status means the port is not in use. This is an example of output from the show interfaces command for an interface:. In the given example, how long has the port been up?

Active--The port made a connection. The other Tengigabit ports numbered 5 to 8 G2 and the Fortygigabit port numbered 10 G4 are disabled by default. The trace command uses the time to live TTL field in the IP header to cause routers and servers to generate specific return messages.

Network or host unreachable—If there is no entry in the route table for the host or network, a Network or Host Unreachable message is returned. If you specify a multicast source or destination MAC address, the path is not identified, and an error message appears. The above counters are useful to check how much traffic has passed through the interface the last 5 minutes. Changing the Logout Timer The logout timer automatically disconnects a user from the switch when the user is idle for longer than the specified time. The physical port might be UP but the protocol might show Down. If any devices in the physical path are transparent to CDP, the switch cannot identify the path through these devices.

This chapter describes how to check switch port status and connectivity on the Catalyst series switch. This chapter includes the following major sections:. The Catalyst series switch is a multimodule system.

Switch Switch traceroute mac ip 1. In those instances, the port on the device should be administratively down before the start of the TDR test. The first router decrements the TTL field by 1 and sends the datagram to the next router. Optional Number of the module. This example shows how to use a ping command in privileged EXEC mode to specify the number of packets, the packet size, and the timeout period:. If you have interface errors the reliability factor will decrease. Would you like to mark this message as the new best answer?
