Question: Why I can’t receive Cisco ws-c3750x-48t-s IP
address from the DHCP server ? Network paralysis or failure should not normal operation. Operating system may prompt the client is currently unable to get the IP address from the DHCP server. Check card state, found no IP address allocation.
Answer:
There is
the reason: Not received from the DHCP server IP address. DHCP server
IP address depletion, the server service is paralyzed, terminal device may be configured to use a static IP address instead of an DHCP distribution,terminal
equipment of the DHCP request never arrives at the server, which may lead to the client could not get the IP address.
Especially
if a new device to configure a virtual local area network (VLAN),no request for establishing connection with the server service, equipmentmust not get the IP address. Is a
new device configuration to an VLAN,without an DHCP request to the DHCP server will lead to relay, request cannot be sent to the DHCP server.
How to
solve:
Please make
sure the client network settings are configured to use theDynamic Host Configuration Protocol (DHCP).
Next, check the switch port is
divided into which VLAN, get the IP address of other devices to the VLAN can check. If they can not get the IP address, the cause of the problem may be the router does not have the DHCP request to the DHCP server. If many equipment multi subnet are having this problem,then it is
likely that the DHCP server problems, namely the DHCP service on the server may not be running, or its IP address has been depleted.
