Digital Modem Statistics
DHCPNAKs rcvd
Incremented whenever the DHCP Proxy Client has received a DHCPNAK message from a DHCP
server.
Invalid DHCP pkts rcvd
Incremented whenever the DHCP Proxy Client encounters a DHCP message that is invalid due to
either of the following:
•
the ’op’ field is not equal to BOOTREPLY
•
the DHCP ’special field’ is not found at the beginning of the options field
When this occurs, the packet is silently discarded.
Invalid XID rcvd
Incremented whenever the DHCP Proxy Client manager receives a DHCP message with a
transaction ID that was not reserved by any of the underlying DHCP client invocations. When this
occurs, the packet is silently discarded.
No xmt buffer available
Incremented whenever the DHCP Proxy Client cannot successfully get a buffer from the Proxy
Client’s transmit buffer pool. This can happen whenever we are trying to send BOOTREQUEST
messages to a DHCP server.
