A configured port on a BAS switch provides an entry point into the BAS network. It is recommended you configure the minimum number of switch ports that are needed. Keep all other switch ports non-configured.

To clear the configuration of a switch port on a Cisco managed switch, complete the following steps.

Table 1. Configuring necessary switch ports on a Cisco managed switch

Configuration step

Cisco IOS CLI command


Enter global configuration mode.

Switch# configure terminal


Clear any existing switch port configurations from unused ports. In this example, the configuration of port gigabitEthernet1/1 is being cleared.

Switch(config)# default interface gigabitEthernet1/1


Exit global configuration mode.

Switch(config)# exit

You must configure only the following switch ports on a Metasys BAS switch:

  • A switch port for each Metasys device to be connected (for example, network engine or IP controllers) to the Metasys BAS switch. Note that when multiple IP controllers are to be configured in a daisy-chain, only a single switch port needs to be configured for the daisy-chain.
  • A switch port for the uplink to the Metasys BAS Aggregation switch or to the IT network. If EtherChannel is being implemented as described in EtherChannel, two switch ports are configured for the uplink to the Metasys BAS Aggregation switch or to the IT network.
  • A switch port to be used to locally connect a maintenance laptop for debugging purposes.
