Description
Number of queries sent by the client to the VMPS.
Number of responses sent to the client from the VMPS.
Number of times that the VMPS changed from one server to another.
Number of times the VMPS sent a response to shut down the port. The client
disables the port and removes all dynamic addresses on this port from the
address table. You must administratively re-enable the port to restore
connectivity.
Number of times the VMPS denied the client request for security reasons.
When the VMPS response denies an address, no frame is forwarded to or
from the workstation with that address. (Broadcast or multicast frames are
delivered to the workstation if the port on the switch has been assigned to a
VLAN.) The client keeps the denied address in the address table as a blocked
address to prevent further queries from being sent to the VMPS for each new
packet received from this workstation. The client ages the address if no new
packets are received from this workstation on this port within the aging time
period.
Number of times the management domain in the request does not match the
one for the VMPS. Any previous VLAN assignments of the port are not
changed. This response means that the server and the client have not been
configured with the same VTP management domain.
Number of times the version field in the query packet contains a value that is
higher than the version supported by the VMPS. The previous VLAN
assignment of the port is not changed. The switches send only VMPS version
1 requests.
Number of times the VMPS is unable to answer the request because of a
resource availability problem. If the retry limit has not yet been reached, the
client repeats the request with the same server or with the next alternate
server, depending on whether the per-server retry count has been reached.
Description
Clears the statistics maintained by the VQP client.
Sends VQP queries to reconfirm all dynamic VLAN assignments with the
VMPS.
Configures the per-server retry count for the VQP client.
Configures the primary VMPS and up to three secondary servers.
