What Is RAPIDCITY-VLAN-MIB?

RAPIDCITY-VLAN-MIB is a Bay Networks/Nortel vendor-specific MIB (registered under enterprises.2272, the 'rapidcity' branch) that models VLAN configuration for Rapid City-based switches, with the file noting minor adaptations for the C100/5000BH environment. Its rcVlanTable, indexed by rcVlanId, carries per-VLAN name, color-coding, routing-enable flag, assigned spanning-tree group (rcVlanStgId), VLAN classification type (byPort, byIpSubnet, byProtocolId, bySrcMac, byDstMcast), IP subnet address/mask for subnet-based VLANs, and 32-octet bitmask fields for port/potential/static membership, alongside an action/result pair (rcVlanAction/rcVlanResult) that lets an administrator trigger table flushes (MAC forwarding table, ARP table, IP route table) per VLAN. A scalar rcVlanNumVlans reports the total VLAN count, and rcVlanRowStatus provides RowStatus-based create/delete control. This gives an operator both VLAN provisioning control and a way to trigger corrective table flushes without a full switch reset. It depends on IF-MIB for the routed VLAN's InterfaceIndex and on legacy RFC1155-SMI/RFC-1212 imports for its SMIv1-era syntax. It is deployed on Nortel/Bay Networks Rapid City switches, and loading a RAPIDCITY-VLAN-MIB MIB Browser session is how an administrator would inspect or reconfigure VLANs on these devices.

IPNetwork Monitor allows you to monitor SNMP objects defined in RAPIDCITY-VLAN-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

Nortel/Bay Networks Rapid City-based switches (C100/5000BH series)

Monitoring Examples

An operator polls rcVlanRoutingEnable and rcVlanIfIndex for a VLAN expected to be routed; an rcVlanIfIndex of zero despite rcVlanRoutingEnable being true would indicate the VLAN's routing interface never came up, explaining why inter-VLAN traffic for that segment is failing.

What Can Be Monitored

VLAN table entries (ID, name, type, port membership)
VLAN count scalar
VLAN action/result (flush MAC FDB/ARP/IP route table)
spanning tree group assignment per VLAN
VLAN row status (create/delete)

OID symbolic	OID numeric	Type	Access	Description
rapidcity	1.3.6.1.4.1.2272
rapidcityfoo	1.3.6.1.4.1.2272.1
rcVlan	1.3.6.1.4.1.2272.1.3
INT rcVlanAction	1.3.6.1.4.1.2272.1.3.2.1.7	INTEGER	read-write	Vlan related actions.
INT rcVlanAgingTime	1.3.6.1.4.1.2272.1.3.2.1.18	INTEGER	read-write	The timeout period in seconds for aging out dynamic members of policy-based VLANs.
INT rcVlanColor	1.3.6.1.4.1.2272.1.3.2.1.3	INTEGER	read-write	Color assigned to this VLAN. The color is a proprietary number scheme used by the DM to associate an integer value with a particular color. The color is treated transparently in the device.
rcVlanEntry	1.3.6.1.4.1.2272.1.3.2.1		not-accessible	Entry containing information for a particular Virtual LAN.
T/F rcVlanHighPriority	1.3.6.1.4.1.2272.1.3.2.1.4	TruthValue	read-write	Control whether this VLAN should be given high priority.
INT rcVlanId	1.3.6.1.4.1.2272.1.3.2.1.1	INTEGER	read-only	A value that uniquely identifies the Virtual LAN associated with this entry. This value correspond to the lower 12 bits in the IEEE VLAN field.
NUM rcVlanIfIndex	1.3.6.1.4.1.2272.1.3.2.1.6	InterfaceIndex	read-only	If rcVlanRoutingEnable is set to TRUE, then this value will indicate the 'logical' ifIndex that is assigned to this VLAN. Otherwise, this value is meaningless and should be set to zero.
MAC rcVlanMacAddress	1.3.6.1.4.1.2272.1.3.2.1.19	MacAddress	read-only	The MAC address assigned to this VLAN. This field is only relevant when the VLAN is configured for routing.
STR rcVlanName	1.3.6.1.4.1.2272.1.3.2.1.2	DisplayString	read-write	VLAN Name
OCT rcVlanNotAllowToJoin	1.3.6.1.4.1.2272.1.3.2.1.14	OCTET STRING	read-write	A bitfield used to identify which ports are not allowed to join this VLAN. A one(1) value in a bit means the port is not allowed to join a VLAN. A zero(0) value in a bit means the port is allowed to join a VLAN. The bitfield is 32 octets long representing ports 0 to 255 (inclusive).
INT rcVlanNumVlans	1.3.6.1.4.1.2272.1.3.1	INTEGER	read-only	Number of VLANs currently defined
OCT rcVlanPortMembers	1.3.6.1.4.1.2272.1.3.2.1.11	OCTET STRING	read-write	A bitfield used to identify which ports in the system are members (static or dynamic) to this VLAN. The bitfield is 32 octets long representing ports 0 to 255 (inclusive).

INT rcVlanProtocolId	1.3.6.1.4.1.2272.1.3.2.1.15	INTEGER	read-write	The protocol id of this VLAN. This value is meaningful only if 'rcVlanType' is equal to 'byProtocolId'.
INT rcVlanResult	1.3.6.1.4.1.2272.1.3.2.1.8	INTEGER	read-only	Result from the last Vlan action.
T/F rcVlanRoutingEnable	1.3.6.1.4.1.2272.1.3.2.1.5	TruthValue	read-write	Control whether routing should be enabled on this VLAN.

OCT rcVlanStaticMembers	1.3.6.1.4.1.2272.1.3.2.1.13	OCTET STRING	read-write	A bitfield used to identify how ports are members of this VLAN. A one(1) value in a bit means the port is a static member of this VLAN. A zero(0) value in a bit means the port is a dynamic member of this VLAN. The bitfield is 32 octets long representing ports 0 to 255 (inclusive).
INT rcVlanStgId	1.3.6.1.4.1.2272.1.3.2.1.9	INTEGER	read-write	Used to indicate the spanning tree group this VLAN is associated it. If this vlan is not be associated with any spanning tree group, this value should be set to zero(0).
IP rcVlanSubnetAddr	1.3.6.1.4.1.2272.1.3.2.1.16	IpAddress	read-write	The IP subnet address of this VLAN. This value is meaningful only if 'rcVlanType' is equal to 'byIpSubnet'.
IP rcVlanSubnetMask	1.3.6.1.4.1.2272.1.3.2.1.17	IpAddress	read-write	The IP subnet mask of this VLAN. This value is meaningful only if 'rcVlanType' is equal to 'byIpSubnet'.
