Module: CIENA-CES-DHCPV6-CLIENT-MIB

OID (symbolic): CIENA-CES-DHCPV6-CLIENT-MIB::cienaCesDhcpv6LdraExceedMTUPktDrop

OID (numeric): 1.3.6.1.4.1.1271.2.1.30.1.2.4.1.9

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: This object specifies the number of DHCPv6 packets dropped because the new relay frame size would exceed the MTU.

What is cienaCesDhcpv6LdraExceedMTUPktDrop?

Counts DHCPv6 packets dropped because adding LDRA's relay-forwarding options would have made the resulting frame exceed the MTU. This is the IPv6 analog of the option-82-exceeds-MTU case seen in DHCP relay, but here the packet is dropped outright rather than forwarded unmodified, so a rising count means some client requests on this VLAN are being lost entirely rather than just missing the extra option data. A long IntID string configured close to the 64-byte maximum, combined with an already-near-MTU network path, would make this counter more likely to climb.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1271.2.1.30.1.2.4.1.9
snmpwalk -v2c -c public <target> CIENA-CES-DHCPV6-CLIENT-MIB::cienaCesDhcpv6LdraExceedMTUPktDrop

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1271.2.1.30.1.2.4.1.9.1
snmpget -v2c -c public <target> CIENA-CES-DHCPV6-CLIENT-MIB::cienaCesDhcpv6LdraExceedMTUPktDrop.1
