hh3cdot1sMstiStpPortAdminBPDUFmt

Module: HH3C-LswMSTP-MIB

OID (symbolic): HH3C-LswMSTP-MIB::hh3cdot1sMstiStpPortAdminBPDUFmt

OID (numeric): 1.3.6.1.4.1.25506.8.35.14.20.1.30

Node type: OBJECT-TYPE

Type: Hh3cdot1sFormatStatus

Access: read-write

Description: The value of the node is an administrative value. Value legacy means that the MST BPDU format is forced to legacy. Value dot1s means that the MST BPDU format is forced to IEEE 802.1s. Value auto means that the format of MST BPDU sending on the port is determined by the MST BPDU that the port has received. Effective in CIST.

What is hh3cdot1sMstiStpPortAdminBPDUFmt?

This OID sets the administrative MST BPDU format for this port, effective in the CIST: legacy forces the old format, dot1s forces IEEE 802.1s format, and auto lets the port match whatever format it receives from its neighbor. Admins use this when a port needs to interoperate with an older bridge that only understands legacy-format BPDUs.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.25506.8.35.14.20.1.30
snmpwalk -v2c -c public <target> HH3C-LswMSTP-MIB::hh3cdot1sMstiStpPortAdminBPDUFmt

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.25506.8.35.14.20.1.30.1
snmpget -v2c -c public <target> HH3C-LswMSTP-MIB::hh3cdot1sMstiStpPortAdminBPDUFmt.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.25506.8.35.14.20.1.30.1 s <value>
