mellanoxXstpVids1
Module: MELLANOX-XSTP-MIB
OID (symbolic): MELLANOX-XSTP-MIB::mellanoxXstpVids1
OID (numeric): 1.3.6.1.4.1.33049.13.1.2.1.1.8
Node type: OBJECT-TYPE
Type: OCTET STRING
Access: read-only
Description: Only relevant for MSTP. The second 1024 bits of the 4096 bit vector indicating which VIDs are assigned to this STID. The high order bit of the first octet corresponds to the first bit of this portion 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 STID.
What is mellanoxXstpVids1?
This octet string holds the second 1024 bits (VLANs roughly 1025-2048) of a 4096-bit bitmap where each set bit marks a VLAN ID that is mapped to this MST instance. Admins decode this bitmap to determine which VLANs in that ID range share this spanning tree instance's topology, since all VLANs on the same MSTI follow the same forwarding and blocking decisions. For example, a set bit near the start of this portion of the vector would indicate VLAN 1025 is assigned to this MST instance.
