fibTmuPortsTauMode

Module: TMU-MIB

OID (symbolic): TMU-MIB::fibTmuPortsTauMode

OID (numeric): 1.3.6.1.4.1.22.60.5.29.1.19

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This is a bit map of information on the status of the Tau and the way it is set. Details of the various bits: Bit0 (= 0x01) If '1' then Tau is set to a rate of 16 mega bits per second on token ring. Otherwise, it is set to a rate of 4 mega bits per second. Only meaningful when 'fibTmuPortsTauPortState' is 'active-connection'.

What is fibTmuPortsTauMode?

This is a bit-mapped field reporting the attached Tau's status and settings: bit0 set (0x01) means the Tau is set to 16 Mbps token ring speed, otherwise it's 4 Mbps; only meaningful when fibTmuPortsTauPortState is active-connection. Admins check it to confirm a Tau is running at the expected ring speed for the deployment. For example, this reveals a speed mismatch if a 4 Mbps Tau was accidentally connected to a 16 Mbps ring segment.
