ctTransFddiAtmMtu
Module: CTRON-TRANSLATION-MIB
OID (symbolic): CTRON-TRANSLATION-MIB::ctTransFddiAtmMtu
OID (numeric): 1.3.6.1.4.1.52.4.1.3.4.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: When written with a (1), allows SNAP frames up to 4500 bytes in length to be received from the FNB and processed by the ATM SAR component. When this object is written with a (1), a value of (1) for the ctTransFddiAtmIPFrag object must be ignored.
When written with a (2), discards any frames received on the FNB which are greater than 1518 bytes in length. A value of (2) must be ignored if the frame is IP and the ctTransFddiAtmIPFrag object is written with a (1).
What is ctTransFddiAtmMtu?
Sets whether frames larger than the standard 1518-byte Ethernet MTU are allowed through the FDDI-to-ATM translation path. greater1518MTU (the default) lets SNAP frames up to 4500 bytes pass to the ATM SAR component, while less1518MTU discards any FNB frame over 1518 bytes unless the IP-fragmentation object below is instead set to fragment. Admins raise this when large-MTU FDDI traffic needs to reach an ATM uplink without being dropped.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.1.3.4.1.1 snmpwalk -v2c -c public <target> CTRON-TRANSLATION-MIB::ctTransFddiAtmMtu
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.1.3.4.1.1.1 snmpget -v2c -c public <target> CTRON-TRANSLATION-MIB::ctTransFddiAtmMtu.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.52.4.1.3.4.1.1.1 i <value>
