A cellular port enables a specific cellular service for an associated SIM. Each cellular port is managed separately per SIM and per PDN.
Cellular port 1/1/1 is associated with SIM 1 and cellular port 1/1/2 is associated with SIM 2.
A cellular port can be shut down by using the port>shutdown command. When a cellular port is shut down, the cellular service for that port is disabled. To enable cellular service for the port, use the port>no shutdown command. See Common configuration commands for more information about the shutdown command.
Use caution when executing the port>shutdown command on a cellular port. Shutting down a cellular port when it is the only means of communication to a remote node over a wireless network may cause permanent loss of connectivity to the node.
