What Is CBS-VAPGROUP-MIB?

CBS-VAPGROUP-MIB is a Cisco-specific MIB for the Cisco Business Series (CBS) switches, covering the wireless Virtual Access Point (VAP) group feature used to load-balance clients across access points. It exposes configuration data such as VAP group membership, load and preemption priorities, and lists of access point managers and load-balancing peers. It includes cbsVapGroupsTraps for event notification and counters like cbsVgVapCount and cbsVgMaxLoadCount that reflect the operational load state of each VAP group, giving visibility into software-level status of the wireless service. It builds on Cisco's standard enterprise MIB conventions and is used alongside other Cisco wireless/VAP MIBs rather than a formal IETF standard. It is typically deployed on Cisco CBS switches running XOS in small-to-midsize wireless LAN deployments to balance client load across access points. Network engineers evaluating or troubleshooting this functionality can download the CBS-VAPGROUP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in CBS-VAPGROUP-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.

Monitoring Examples

An administrator could poll cbsVapGroupTable/cbsVapGroupEntry entries to see each cbsVgVapGroupID with its cbsVgVapCount and cbsVgMaxLoadCount, flagging a group that is at or near capacity and needs load redistribution. Monitoring cbsVgLoadPriority and cbsVgPreempPriority together with cbsVgBackUpMode can reveal whether a failover/backup VAP group has taken over unexpectedly. cbsVapGroupsTraps would notify when group membership or load state changes.

What Can Be Monitored

VAP group membership
VAP count per group
load/preemption priority
max load count
backup mode state
load balancing list

cbsVapGroupTable	1.3.6.1.4.1.6848.2.4.1		not-accessible	This table contains information about the VAP groups.
cbsVapMappingEntry	1.3.6.1.4.1.6848.2.4.2.1		not-accessible	An entry in the vap mapping table.
cbsVapMappingTable	1.3.6.1.4.1.6848.2.4.2		not-accessible	This table contains information about how the individual VAPs are mapped to hardware modules.
NTF cbsVapStatusChanged	1.3.6.1.4.1.6848.4.3.1			The VAP status for the given VAP changed.
STR cbsVgApmList	1.3.6.1.4.1.6848.2.4.1.1.5	DisplayString	read-only	The APMs that are potentially assigned to support this VAP group.
INT cbsVgBackUpMode	1.3.6.1.4.1.6848.2.4.1.1.9	INTEGER	read-only	Specifies how to perform a backup in case an APM fails. None - no backup Pair - VAPs are paired to provide backup functionality Group - all VAPs in the group back up each other.
I32 cbsVgDelayFlow	1.3.6.1.4.1.6848.2.4.1.1.15	Integer32	read-only	Specifies the delay time, in seconds, after the VAP has come up before starting to load balance traffic to this VAP.
T/F cbsVgIpForward	1.3.6.1.4.1.6848.2.4.1.1.10	TruthValue	read-only	Specifies if IP forwarding is enabled or not.
T/F cbsVgIpv6Forward	1.3.6.1.4.1.6848.2.4.1.1.16	TruthValue	read-only	Specifies if IPv6 forwarding is enabled or not.
