ieee8021MstpVids0

Module: IEEE8021-MSTP-MIB

OID (symbolic): IEEE8021-MSTP-MIB::ieee8021MstpVids0

OID (numeric): 1.3.111.2.802.1.1.6.1.2.1.11

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: This object contains the first 1024 bits of the 4096 bit vector indicating which VIDs are assigned to this MSTID. The high order bit of the first octet corresponds to the first bit of the vector, while the low order bit of the last octet corresponds to the last bit of this portion of the vector. A bit that is on (equal to 1) indicates that the corresponding VID is assigned to this MSTID.

What is ieee8021MstpVids0?

A 1024-bit bitmap (VIDs 1-1024, one bit per VLAN, high bit of the first octet = first VID) showing which VLANs are mapped to this MST Instance; a set bit means that VLAN's traffic follows this instance's spanning tree.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.6.1.2.1.11
snmpwalk -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpVids0

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.111.2.802.1.1.6.1.2.1.11.1
snmpget -v2c -c public <target> IEEE8021-MSTP-MIB::ieee8021MstpVids0.1
