What Is BASIS-SERIAL-MIB?
BASIS-SERIAL-MIB is a Cisco MIB for the MGX 8850/8250/8220 ATM Edge switch family (BASIS shelf architecture), managing serial port configuration and status on the shelf's Processor Module and various service module cards. It exposes a serial interface table describing each serial port's number, type, enable state, and baud rate (bps), along with a count of valid entries, characterizing it as both a configuration and status MIB for the shelf's auxiliary serial connectivity. It supports monitoring of hardware port status on the switch shelf — confirming serialPortEnable and serialPortbps match expected settings per port helps detect a misconfigured or disabled serial port used for console/craft or auxiliary connections on the ATM edge switch modules. It appears to be a self-contained Cisco-proprietary MIB specific to the MGX/BASIS shelf architecture, without dependency on other MIBs evident from context. It is typically deployed by carriers operating Cisco MGX 8850/8250/8220 ATM edge switches in legacy ATM/frame-relay access networks, and the BASIS-SERIAL-MIB download is available from Cisco's MIB archive for loading into a MIB browser alongside the shelf's other BASIS-family MIBs.
IPNetwork Monitor allows you to monitor SNMP objects defined in BASIS-SERIAL-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.
Supported Devices
- Cisco MGX 8850 ATM edge switch
- Cisco MGX 8250/8220 ATM edge switch
Monitoring Examples
An administrator would poll serialInterfaceTable/serialInterfaceEntry for a given serialPortNum to check serialPortType, serialPortEnable, and serialPortbps, confirming the serial port on a given processor or service module card is enabled and running at the expected baud rate. serialPortNumOfValidEntries indicates how many serial ports are recognized on the shelf, and a lower-than-expected count could reveal a card that failed to register its serial ports after insertion or reboot.
What Can Be Monitored
- serial port type
- serial port enable state
- serial port baud rate (bps)
- number of valid serial port entries
