Cisco ASA 5500 Series Configuration Guide using ASDM
8-34
Temp IP addr—Display only. The IP address assigned to the interface.
Temp sub net mask—Display only. The subnet mask assigned to the interface.
DHCP lease server—Display only. The DHCP server address.
state—Display only. The state of the DHCP lease, as follows:
Initial—The initialization state, where the security appliance begins the process of acquiring a
lease. This state is also shown when a lease ends or when a lease negotiation fails.
Selecting—The security appliance is waiting to receive DHCPOFFER messages from one or
more DHCP servers, so it can choose one.
Requesting—The security appliance is waiting to hear back from the server to which it sent its
request.
Purging—The security appliance is removing the lease because of an error.
Bound—The security appliance has a valid lease and is operating normally.
Renewing—The security appliance is trying to renew the lease. It regularly sends
DHCPREQUEST messages to the current DHCP server, and waits for a reply.
Rebinding—The security appliance failed to renew the lease with the original server, and now
sends DHCPREQUEST messages until it gets a reply from any server or the lease ends.
Holddown—The security appliance started the process to remove the lease.
Releasing—The security appliance sends release messages to the server indicating that the IP
address is no longer needed.
Lease—Display only. The length of time, specified by the DHCP server, that the interface can
use this IP address.
Renewal—Display only. The length of time until the interface automatically attempts to renew
this lease.
Rebind—Display only. The length of time until the security appliance attempts to rebind to a
DHCP server. Rebinding occurs if the security appliance cannot communicate with the original
DHCP server, and 87.5 percent of the lease time has expired. The security appliance then
attempts to contact any available DHCP server by broadcasting DHCP requests.
Next timer fires after—Display only. The number of seconds until the internal timer triggers.
Retry count—Display only. If the security appliance is attempting to establish a lease, this field
shows the number of times the security appliance tried sending a DHCP message. For example,
if the security appliance is in the Selecting state, this value shows the number of times the
security appliance sent discover messages. If the security appliance is in the Requesting state,
this value shows the number of times the security appliance sent request messages.
Client-ID—Display only. The client ID used in all communication with the server.
Proxy—Display only. Specifies if this interface is a proxy DHCP client for VPN clients, True
or False.
Hostname—Display only. The client hostname.
