ipv4Mtu
Module: CORIANT-GROOVE-MIB
OID (symbolic): CORIANT-GROOVE-MIB::ipv4Mtu
OID (numeric): 1.3.6.1.4.1.42229.1.2.6.5.1.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The size, in octets, of the largest IPv4 packet that the interface will send and receive.
The server may restrict the allowed values for this leaf, depending on the interface's type.
If this leaf is not configured, the operationally used MTU depends on the interface's type.
UNITS:octets
What is ipv4Mtu?
This field specifies, in octets, the largest IPv4 packet size the interface will send and receive, constrained between 68 and 65535, with the operational MTU depending on interface type if left unconfigured. An admin adjusts this when packets are being fragmented or dropped due to a path MTU mismatch, or to accommodate jumbo frames on interfaces that support them. Lowering this MTU on a management interface traversing a tunnel with extra encapsulation overhead is a typical reason to override the default.
