mSTInstanceVlansMapped3k

Module: PRVT-MST-MIB

OID (symbolic): PRVT-MST-MIB::mSTInstanceVlansMapped3k

OID (numeric): 1.3.6.1.4.1.738.1.5.107.1.1.2.5.1.4

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-only

Description: A string of octets containing one bit per VLAN for VLANs with VlanIndex values of 2048 through 3071. The first octet corresponds to VLANs with VlanIndex values of 2048 through 2055; the second octet to VLANs 2056 through 2063; etc. The least significant bit of each octet corresponds to the lowest value VlanIndex in that octet.

For each VLAN, if it is mapped to this MST instance, then the bit corresponding to that VLAN is set to '1'.

What is mSTInstanceVlansMapped3k?

This read-only bitmap is the continuation of the VLAN-to-instance mapping covering VLANs 2048-3071, extending the picture of which VLANs this MST instance governs into that range.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.738.1.5.107.1.1.2.5.1.4
snmpwalk -v2c -c public <target> PRVT-MST-MIB::mSTInstanceVlansMapped3k

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.738.1.5.107.1.1.2.5.1.4.1
snmpget -v2c -c public <target> PRVT-MST-MIB::mSTInstanceVlansMapped3k.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> mSTInstanceVlansMapped3k.1
