cmEthernetMgmtPortMTU
Module: CM-FACILITY-MIB
OID (symbolic): CM-FACILITY-MIB::cmEthernetMgmtPortMTU
OID (numeric): 1.3.6.1.4.1.2544.1.12.4.1.9.1.6
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This object provides the MTU on the Ethernet Management Port.
What is cmEthernetMgmtPortMTU?
This read-only Integer32 reports the MTU currently in effect on an Ethernet Management Port. Admins reference this when troubleshooting fragmented or dropped management-protocol traffic (such as large SNMP responses or file transfers over the management interface), since it's read-only and reflects a fixed platform value rather than something they can tune. For example, if large SNMP bulk-walk responses over the management port are being truncated, an admin would check cmEthernetMgmtPortMTU to confirm the port's fixed MTU is sufficient for the response size before looking elsewhere for the cause.
Examples
