Description
IP address leased from the DHCP server for the cable access router interface.
Temporary subnet mask assigned to the cable access router interface.
IP address of the DHCP server that assigned an IP address to this client.
Current state of this client (the cable access router interface). Possible states are Bound,
Renew, or Rebinding. For descriptions of these states, see RFC 2131.
Unique number established by the Cisco uBR924 before the first request message is
sent to the DHCP server. The same transaction id is used as long as the lease keeps
getting renewed and is valid. If a new "discover" message is sent, a new transaction id is
used.
Time (in seconds) for which the leased IP address is valid; the duration of the lease.
Time interval (in seconds) from address assignment until the client transitions to the
renewing state. When the renewal (T1) time expires, the client sends a unicast
dhcprequest message to the server to extends its lease. The default value of this timer is
0.5 times the duration of the lease.
Time interval (in seconds) from address assignment until the client transitions to the
rebinding state and sends a broadcast dhcprequest message to any DHCP server to
extends its lease. The default value of this timer (T2) is 0.875 times the duration of the
lease.
IP address of the router closest to this client on the network.
Time in hours, minutes, and seconds until the next timer expires.
Number of times the client has sent any message to the DHCP server -- most likely a
request message to extend its lease. When the lease is renewed, the Retry count is reset
to 0.
MAC address (with optional media type code) that uniquely identifies the client on the
subnet for binding lookups.

Description
MAC address used by the DHCP server.
Number of current leased IP addresses.
Number of offers for an IP address sent to a proxy-client from the server.
