Description: Extends IEEE 802.1X EAPOL authentication configuration and per-port supplicant status on Avaya/Nortel ERS.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is BAY-STACK-EAPOL-EXTENSION-MIB?

BAY-STACK-EAPOL-EXTENSION-MIB is an Avaya/Nortel (BayStack/ERS switch family) proprietary extension to standard IEEE 802.1X EAPOL port-based authentication, adding vendor-specific policy controls. It exposes configuration objects for guest and remediation VLAN assignment, maximum EAP/non-EAP client MAC counts per port, multi-host authentication behavior, and user-based policy filtering by MAC address, plus a notifications group for authentication-related events. Its monitoring/management emphasis is on network access control state rather than hardware health: it lets an admin verify whether guest-VLAN or remediation-VLAN redirection is enabled and correctly configured, and whether ports are enforcing single-auth versus multi-host client limits. It explicitly builds on and extends the standard IEEE8021-PAE-MIB (802.1X EAPOL) rather than replacing it, so it is always used alongside that base MIB. It is typically deployed on Avaya/Nortel Ethernet Routing Switches in enterprise networks, where BAY-STACK-EAPOL-EXTENSION-MIB SNMP monitoring supports 802.1X port authentication with guest/remediation VLAN workflows.

IPNetwork Monitor allows you to monitor SNMP objects defined in BAY-STACK-EAPOL-EXTENSION-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

  • Avaya/Nortel BayStack Ethernet Routing Switch (ERS)

Monitoring Examples

A network admin would check bseeGuestVlanEnabled and bseeGuestVlanId together with bseeRemediationVlanEnabled and bseeRemediationVlanId to confirm unauthenticated or failed-posture clients land on the correct VLAN, and bseeMaximumEapClientMacs/bseeMaximumNonEapClientMacs to verify per-port client-count limits are enforced as configured. If bseeMultiHostSingleAuthEnabled is set but multiple non-EAP MACs are appearing, bseeMultiHostAllowNonEapClient and bseeMultiHostRadiusAuthNonEapClient help explain why, and bseeNotifications events would flag authentication state changes for real-time alerting. bseeUserBasedPoliciesFilterOnMac indicates whether MAC-based policy filtering is active on the port.

What Can Be Monitored

  • guest VLAN enable/ID
  • remediation VLAN enable/ID
  • max EAP client MACs per port
  • max non-EAP client MACs per port
  • multi-host authentication mode
  • user-based policy MAC filtering state
