civrTopologyActiveSwitchVsan2k

Module: CISCO-IVR-MIB

OID (symbolic): CISCO-IVR-MIB::civrTopologyActiveSwitchVsan2k

OID (numeric): 1.3.6.1.4.1.9.9.371.1.1.5.8.1.3

Node type: OBJECT-TYPE

Type: FcList

Access: read-only

Description: The list of VSANs that are part of IVR topology on this device.

Each octet within the value of this object specifies a set of eight VSANs, with the first octet specifying VSANs 0 through 7, the second octet specifying VSANs 8 through 15, etc. Within each octet, the most significant bit represents the lowest numbered VSAN, and the least significant bit represents the highest numbered VSAN. Thus, each VSAN, is represented by a single bit within the value of this object. The corresponding VSAN is contained in the IVR topology on this device if and only if that bit has a value of '1'. If this object has a value which is less than 256 bytes long, then the VSANs which are not represented are not considered to be in this list.

If the values of both this object and corresponding instance of civrTopologyActiveSwitchVsan4k are zero-length string, then the IVR topology contains only the default VSAN.

What is civrTopologyActiveSwitchVsan2k?

Reports, as a bitmap, which VSANs (numbered 0-2047) are part of the active IVR topology on this switch, with each octet encoding eight VSAN memberships.

Examples
