hh3cVsanDmPrincipalSwitchWWN
Module: HH3C-VSAN-MIB
OID (symbolic): HH3C-VSAN-MIB::hh3cVsanDmPrincipalSwitchWWN
OID (numeric): 1.3.6.1.4.1.25506.2.127.1.1.1.2.1.11
Node type: OBJECT-TYPE
Type: Hh3cFcNameId
Access: read-only
Description: Indicates the WWN of the principal switch in this VSAN, or zero-length string if the identity of the principal switch is unknown.
What is hh3cVsanDmPrincipalSwitchWWN?
This read-only value reports the World Wide Name of the switch currently acting as principal switch in this VSAN, or a zero-length string if that identity isn't yet known. Admins use this to identify which device is responsible for domain ID assignment and fabric-wide coordination in a VSAN, which is important when diagnosing domain ID assignment failures. For example, an admin can compare hh3cVsanDmPrincipalSwitchWWN across all switches in the same VSAN to confirm they all agree on the same principal switch, which is a common check after a suspected fabric split.
