Cisco show interface transceiver

Cisco switches are complex and dynamic devices that are used for connecting different networking devices within an organization. They utilize different ports and modules that help them perform different functions. One of cisco show interface transceiver most important modules used in Cisco switches is the SFP module. In this article, we will discuss the steps to check the SFP module in a Cisco switch.

In order to check an SFP module in a Cisco switch, there are a few commands that can be used to verify its status and functionality. These commands can help identify if there are any issues with the module or if it is operating normally. This command will display the status of all interfaces on the switch, including the SFP module. If it does not show up, it could indicate a problem with the module. This command will provide detailed information about the SFP module, including its type, temperature, power levels, and other parameters. This can be useful in diagnosing any problems with the module or troubleshooting any performance issues. In addition to these commands, there are also specific commands that can be used to test the SFP module.

To display system information for a SPA interface processor SIP or other module to troubleshoot a problem, use the show hw-module slot tech-support command in privileged EXEC configuration mode. Refer to the appropriate hardware manual for slot information. Use the show hw-module slot tech-support command to gather information about the SIP or other module to troubleshoot a problem. Certain error messages request that you gather this information and have it available when reporting a problem to Cisco Systems technical support personnel. The show hw-module slot tech-support command runs a collection of different show commands to gather information about your system environment and configuration. The following example shows system information for the SIP installed in slot 5 of the router:. To display diagnostic information about internal hardware devices for a SPA, use the show hw-module subslot command in privileged EXEC configuration mode.

Max--Maximum size of the queue.

Units of measurement As seen in the brocade sfpshow output, the light level is represented in dBm and uW. A reading of 0 dBm is 1mW. Also displayed is the light power in uW. Understand readings Once the TX and RX power readings are within the limits that are provided in the command output the SFP is receiving and transmitting light within acceptable levels, because they receive power as measured on an SFP is subject to several external factors:. NOTE: The number 1 issue related to link related problems are dirty cables and optics, many times it is incorrectly assumed to be a faulty optic. Example would be when in a scenario where a new higher speed 16 Gb switch is rolled into an existing environment and then old and existing hosts and targets are installed with existing fiber cables. This is such a wide spread and common event that there is an optic cleaning kit available with the Dell field team to alleviate these issues.

This example shows how to display the summary configuration information of the specified interface:. To display detailed information about the capabilities of an interface, use the show interface capabilities command. Specifies an Ethernet interface slot number and port number. The slot number is from 1 to , and the port number is from 1 to You can use the show interface capabilities command only for physical interfaces.

For IPv6 it is the number of IPv6 software switched characters received for the specified protocol. Optional Displays interface Ether Channel information. If there are any issues with the SFP module, it may need to be replaced. The table below shows other data given for each SDLC secondary interface configured to be attached to this interface. Sliding shelf. Note that this might not balance with the sum of the enumerated output errors, because some datagrams can have more than one error, and others can have errors that do not fall into any of the specifically tabulated categories. In the following example, for the line starting with Full Duplex , the interface port media type is: Virtual , not a physical media type such as RJ Maximum transmission unit of the interface. Displays operational status for the specified transceiver. The following is sample output from the show interfaces command for serial interface 2 when Airline Control ALC Protocol is enabled:. Chassis slot number.

Optional Displays interface MAC accounting information. When you execute the "show interface transceiver" command on a Cisco device, it will display the status of all the SFP modules installed on the device. Output queue, drops input queue, drops. This command was introduced on the Supervisor Engine Find Matches in This Book. The following is sample output from the show interfaces tengigabitethernet command for the only interface port 0 in a 1-Port 10 Gigabit Ethernet SPA located in the top subslot 0 of the carrier card that is installed in slot 7 on a Cisco series router:. Verify the SFP module's wavelength. This command is useful for troubleshooting and monitoring the health of SFP modules. Includes runts, giants, no buffer, cyclic redundancy check CRC , frame, overrun, and ignored counts. Optional Number of the CPU 0 or 1 for which you want to display data. In addition to these commands, there are also specific commands that can be used to test the SFP module. For tunnel interfaces, the IPv6 input packets are counted as IPv6 packets only. Type of ARP assigned and the timeout period. The following reasons are not applicable to every SPA and can be platform-specific.
