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 cisco port status command 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 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 2qq syndrome 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.

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.

Cisco port status command

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. Number of transmit errors that occurred on the port indicating that the internal transmit buffer is full. Number of receive errors that occurred on the port indicating that the internal receive buffer is full. Number of received frames less than 64 octets long but are otherwise well-formed. Number of times one collision occurred before the port successfully transmitted a frame to the media.

I think I have edit the script to now work with ELS code.

You can see which modules are installed, and the MAC address ranges and version numbers for each module, by entering the show module command. You can view the summary or detailed information on the switch ports using the show interface 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. This command works on both Cisco Switches and 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. The above gives me a quick status update of each available interface on the switch, on which VLAN it belongs, speed settings etc. Now if you want to dive deeper in the counters for each physical interface, we can be more specific as shown below:. The most important data you need to take into consideration are the following:. Hardware is Lance, address is b.

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. To display summary information on all of the ports on the switch, enter the show port command with no arguments. Specify a particular module number to see information on the ports on that module only.

Skip auxiliary navigation Press Enter. The second router sees a TTL value of 1, discards the datagram, and returns the Time-Exceeded message to the source. Learn how your comment data is processed. Connecting--The port attempted to connect, or was disabled. TDR detects a cable fault by sending a signal along its wires. These features are available on all releases subsequent to the one they were introduced in, unless noted otherwise. The traceroute mac ip command output shows the Layer 2 path when the specified source and destination IP addresses belong to the same subnet. The above counters are also useful to watch how much traffic has passed through the interface, if there were any errors or frame collisions, buffer failures etc. The documentation set for this product strives to use bias-free language. Depending on the reflected signal, it can determine roughly where a cable fault could be. One for port numbers 5 to 8, termed G2 One for port number 9, termed G3 One for port number 10, termed G4 Ports 1 to 8 are tengigabit ports and ports 9 and 10 are fortygigabit ports. Would you like to mark this message as the new best answer? This also not exists on EX Expand all Collapse all sort by most recent sort by thread.

If you connect a port undergoing a TDR test to a BASE-T port such as that on the device, the unused pairs and are reported as faulty because the remote end does not terminate these pairs. Due to cable characteristics, you should run the TDR test multiple times to get accurate results.

This site uses Akismet to reduce spam. To establish a Telnet connection to another device on the network from the switch, enter this command:. To apply configuration commands to a particular port, you must specify the appropriate logical module. Note Four pairs of standard category 5 cable exist. These features are available on all releases subsequent to the one they were introduced in, unless noted otherwise. To set the logout for 10 minutes and 10 seconds, enter the following command: Switch config line console 0 Switch config-line exec-timeout 10 10 To set no logout timer for console session: Switch config line console 0 Switch config-line exec-timeout 0 0 Monitoring User Sessions You can display the currently active user sessions on the switch using the show users command. It determines the path by using the MAC address tables of the switches in the path. Number of times the port sensed a carrier to determine whether the cable is currently being used. The most important data you need to take into consideration are the following:. A 1.
