How Gigamon switches open ports and read optical module information

      Previously we introduced the use of different brands of switches in the port are the default open state, you can directly access the optical module to read the information, while some of the equipment port default closed state, such as routers, you need to manually set up the port to open; today we are going to introduce the device port is also the default closed state, so the next step to take a look at the Gigamon switch in the use of optical modules before Then we will show you how to configure the ports of Gigamon switches before using optical modules, and how to view the information of the access optical modules.
      The following is an example of accessing Gigamon GigaVUE-TA101 switch with moduletek limited SFP-10G-SR optical module to show you how to set up the port and read the information of the accessed optical module on Gigamon.

1. Port Status View
      Execute the command "show port " to check the status of all ports, the Admin item is disable, which means the port is administratively closed;

      The output information under this command contains interface type, rate, module type, administrative status, etc. (Admin is enable as a prerequisite for the port to be usable).

Figure 2 Port Status

2. Enable Port
      In privileged mode, execute the command "port port-id params admin enable" to enable the port administratively, and the port is now available;
      Explanation: port-id is the interface where the module is located, the format is ＜box-id＞＜slot-num＞＜port-num＞, for example, 1/1/x18; you can execute the command "show port" to check it.
      The rate indicated by the port letter: g=1Gb, x=10Gb, q=40Gb, c=100Gb.

3. View the information of the access optical module
      Execute the command "show port params port-list port-id " to view the information of the optical module on the interface of the device, link status, identification, DOM are integrated under this command (the output is different for different device models or system versions);
      The information output under this command, such as port link status, module type, rate, serial number, vendor information, transmit light, etc., originates from the coded data written by the optical module, and the port type, administrative status, duplex mode, etc., originates from the port configuration parameters.
