Access: read-only

Description: A string of octets containing one bit per VLAN for VLANS with VlanIndex values 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 most significant bit of each octet corresponds to the lowest VlanIndex value in that octet.

For each VLAN that is mapped to this MSTP instance, the bit corresponding to that VLAN is set to '1'.

This object is only instantiated on devices with support for VlanIndex values up to 4095.

What is dot1sInstanceVlanMapped3k?

Reports a bitmask showing which VLANs in the range 2048 through 3071 are currently mapped to a given MSTP instance. It covers the third segment of the VLAN ID space for MSTP instance membership reporting.
