cieSystemMtu
Module: CISCO-IF-EXTENSION-MIB
OID (symbolic): CISCO-IF-EXTENSION-MIB::cieSystemMtu
OID (numeric): 1.3.6.1.4.1.9.9.276.1.2.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: Global system MTU in octets. This object specifies the MTU on all interfaces. However, the value specified by cieIfMtu takes precedence for an interface, which means that the interface's MTU uses the value specified by cieIfMtu, if it is configured.
What is cieSystemMtu?
A read-write global setting specifying the MTU (in octets) applied to all interfaces on the system, unless overridden by a per-interface cieIfMtu value.
Examples
