Cisco port status command

It can be very useful at troubleshooting connectivity issues and physical port issues, check the status of physical ports, cisco port status command, watch how much traffic is passing through the interface, which IP address is assigned to the interface for Layer3 interfaces etc. This command works on both Cisco Switches and Cisco Routers and has the same cisco port status command 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. The above gives me a quick status update of each available interface on the switch, on which VLAN it belongs, speed settings etc.

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. Duplex setting for the port auto, full, fdx, half, hdx, a-half, a-hdx, a-full, a-fdx. Number of frames with alignment errors frames that do not end with an even number of octets and have a bad CRC received on the port.

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.

If you have interface errors the reliability factor will decrease.

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? Impossible to tell.

Cisco port status command

This chapter describes how to check switch port status and connectivity on the Catalyst enterprise LAN switches. The Catalyst enterprise LAN switches are multimodule systems. You can see what modules are installed, as well as the MAC address ranges and version numbers for each module, by using the show module command. The Catalyst G, G, and G switches are fixed-configuration switches, but are logically modular. You must apply configuration commands to the appropriate module. For example, on a Catalyst G series switch, the 24 Fast Ethernet ports belong logically to module 2. This example shows how to check module status on a Catalyst G switch:. You can display summary or detailed information on the switch ports using the show port command.

Good luck Attachment s. Just tested this Junos Automation slax op script and it works well just missing the description field you may be used to in Cisco. To apply configuration commands to a particular port, you must specify the appropriate logical module. This example shows how to use the traceroute command to display the route that a packet takes through the network to reach its destination:. Number of received frames less than 64 octets long but are otherwise well-formed. Connecting--The port attempted to connect, or was disabled. Learn how your comment data is processed. The other Tengigabit ports numbered 5 to 8 G2 and the Fortygigabit port numbered 10 G4 are disabled by default. Number of frames with alignment errors frames that do not end with an even number of octets and have a bad CRC received on the port. Example This example shows how to use the traceroute command to display the route that a packet takes through the network to reach its destination: Switch traceroute ip ABA. A ping returns one of the following responses:. Layer 2 traceroute supports only unicast source and destination MAC addresses. This example shows how to establish a Telnet connection from the switch to the remote host named labsparc:. Bias-Free Language The documentation set for this product strives to use bias-free language. Following is the output of show hardware led command.

Ask questions and share experiences about EX and QFX portfolios and all switching solutions across your data center, campus, and branch locations. An ACL is a packet filtering mechanism which controls IP packets passing through the interface block or allow based on IP address and port numbers. The Command-Change only is not enough. Yes No Feedback. Skip auxiliary navigation Press Enter. Feature History for Checking Port Status and Connectivity This table provides release and related information for features explained in this module. Example This example shows how to use the traceroute command to display the route that a packet takes through the network to reach its destination: Switch traceroute ip ABA. The physical port might be UP but the protocol might show Down. Number of times multiple collisions occurred before the port successfully transmitted a frame to the media. Learn how to become a member. Current configuration : 52 bytes! Connected to labsparc. TDR results might differ between runs on different Catalyst modules because of the resolution difference of TDR implementations. Maybe Andy can help,.
