The customer tried to use the following SNMP OID enterprises.9.9.2126.96.36.199 on the Catalyst ME3400 with 12.2.44SE. From the SNMP object navigator this MIB exists in this IOS. But when the customer used the snmpwalk the following message appeared:
SNMPv2-SMI::enterprises.9.9.2188.8.131.52 = No Such Instance currently exists at this OID.
Do you know if this OID is correct for system MTU on this platform??
