civrTopologyActiveSwitchVsan4k

Module: CISCO-IVR-MIB

OID (symbolic): CISCO-IVR-MIB::civrTopologyActiveSwitchVsan4k

OID (numeric): 1.3.6.1.4.1.9.9.371.1.1.5.8.1.4

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 2047 through 2054, the second octet specifying VSANs 2055 through 2062, 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 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 the list.

If the values of both this object and corresponding instance of civrTopologyActiveSwitchVsan2k are zero-length string, then the IVR topology contains only the default VSAN.

What is civrTopologyActiveSwitchVsan4k?

Reports, as a bitmap, which higher-numbered VSANs (starting at 2047) are part of the active IVR topology on this switch, extending the VSAN range beyond the first 2048.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.371.1.1.5.8.1.4
snmpwalk -v2c -c public <target> CISCO-IVR-MIB::civrTopologyActiveSwitchVsan4k

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.371.1.1.5.8.1.4.1
