cat2600TsPortDuplex
Module: CAT2600-MIB
OID (symbolic): CAT2600-MIB::cat2600TsPortDuplex
OID (numeric): 1.3.6.1.4.1.9.1.111.1.2.2.1.1.21
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Version 1 MIB
When read, this object indicates the Port Duplex state
obtained by the auto-detect function.
This object is a valid read object any time that
TSPortLinkState indicates up(1) or when TsPortFixedCfg
indicates fixed(2).
Write to this object when defining the Port Duplex state
for a fixed configuration (TsPortFixedCfg set to fixed(2)).
Version 2 MIB
This object is related to the dtrMac MIB objects
cPortProtocolCharCurrentAccessProtocol
and cPortProtocolCharAccessProtcolMask
as defined in the following table:
TsPortLinkState | TsPortFixedCfg | TsPortDuplex equivalent to:
| |
down | auto | CPortProtocolCharAccess
| | ProtocolMask = X'0003'
| |
down | fixed | CPortProtocolCharAccess
| | ProtocolMask = X'0001' or
| | = X'0002'
| |
up | auto | cPortProtocolCharCurrent
| | AccessProtocol
| |
up | fixed | cPortProtocolCharCurrent
| | AccessProtocol.What is cat2600TsPortDuplex?
This reports (in auto-detect, when link is up or fixed config applies) or lets the admin force the port's duplex setting, mirroring the same auto-detect/fixed logic used elsewhere in this Token-Ring-capable MIB, and it corresponds to related dtrMac MIB objects for duplex state. An admin forces this to full-duplex(2) on a fixed configuration when connecting to a device known to support it, avoiding the collisions and retransmissions that a half/full duplex mismatch causes. A port stuck reporting half-duplex(1) against a device the admin knows supports full duplex is a classic cause of unexplained CRC and late-collision errors on that link.
