Cisco Switches :: Configure DHCP Server Options For SMB 300?
Nov 28, 2011
I am looking for a how to configure a DHCP server for a Cisco SMB 300 series switch to obtain an automatic configuration. Currently i am using a Cisco 1800 router as my DHCP server and the DHCP pool serving the 300 series switch is configured as follows.
ip dhcp pool Cisco_SMB_300
network 192.168.0.0 255.255.255.0
default-router 192.168.0.1
[Code]......
Looking at pcaps, I don't even see a tftp request going the server after the switch obtains an IP via DHCP. The config file format is exactly as obtained from the download backup section (pretty sure its not the issue since i don't see a download attempt). Also, the SMB switch is running the latest firmware image (1.1.1.8)
Looking though the admin guide i did not see specifics on how the DHCP server was to be configure for the auto configuration feature to work.

I am using a fiber optic connection. I want to connect it directly to ASA5510. A WLC2504 will be connected to ASA and one Aironet AP will be deployed at first. (At this moment I am not using any Windows server but in near future I will need to deploy Windows Server 2003 in my corporate network) My questions are:
Can I configure ASA as DHCP server for my LAN?
Can I configure WLC as DHCP server for my LAN?
If we can configure both then what is the best practice from above two options? (I am new to Cisco stuff and first time user)

I want to set up a domain for a file server and MS SQL 2005 server on my server machine and installed windows server 2008 in it.
Do I need to set up DHCP server and DNS on Windows server 2008R2 or leave them to the router to do the job?

We've just started with the ASA 5505. We do run a DHCP server on the inside interface, so it is in the same VLAN 1 as all of the clients. However, we cannot get it to work.We can't use DHCP Relay, as the ASA 5505 only allows to relay to DHCP servers in a different subnet.Or do we have to move the DHCP server to a different subnet. If so, how would we configure that scenario?

I am trying to configure two 3845 routers to act as dhcp server and dhcp relay. Clients are connected to the router that relays all dhcp requests to the vrf instance which is used to connect it to the router wich is running dhcp server.
Router1
ip vrf dhcp_dns
rd 8:1
int gi0/0
ip vrf forwarding dhcp_dns
ip address 192.168.200.5 255.255.255.248
[code]...
So far I can see dhcp requests coming from the R1 and dhcp server on R2 replies with the dhcp offer but PC is not getting any ip.

Is there a way to configure a DHCP server for my internal subnet of 192.168.20.1 which is on a 3550 layer 3 switch from my 5505 ASA Firewall.My subnet of 10.1.1.0/30 is connecting my 5505 to 3550. All I'm trying to do is run a DHCP server down to my hosts. The only options on ASA 5505 is
dhcpd address 192.168.20.1 - 192.168.20.254 outside or inside, which conflicts with my subnet of 10.1.1.0 used to connect my internal subnet of 192.168.20.1 for the whole network.
When I used my router it did not need the (inside, outside) keywords and just an ip helper-address command. How do I configure my my firewall DHCP server to propagate the 192.168.20.0 network through my 10.1.1.0 connection.

I need to configure a Cisco 2960 switch as a DHCP server. The current IP address will be on a different seed than the DHCP addresses. i.e.
Switch IP = 10.1.2.3, GW = 10.1.2.1, Subnet = 255.255.255.0
DHCP addresses would be 192.168.1.1 - 200, GW=???? (10.1.2.3?) and subnet would be 255.255.255.0

we are looking to use the new firmware's DHCP server feature to setup different DHCP scopes for 5 different VLANs configured on the switch. I see where to turn this on and setup the scope however I can't clearly see where I can assign the specified scope to each VLAN on the switch.

I am relatively new the configuring network switches. Could someone point me in right direction to configure SG300-28 as a DHCP server?
From the people I talked based on device specs it should be able to act as dhcp server. However, if we cannot, can it be configured so that clients get DHCP information from Firewall to which L3 switch is connected.

Firmware 1.3 introduced a DHCP server.
It seems that I can add a pool for any subnet except the 192.168.1.1/24. I have successfully added a pool for 192.168.0.1/24, 172.16.16.1/24, etc. But when I use the same commands to add a 192.168.1.1/24 pool, I get:
sw(config)#ip dhcp pool network Device sw(config-dhcp)#address low 192.168.1.20 high 192.168.1.250 255.255.255.0 Illegal IP addresses range or subnet configuration Trying to configure a network pool on default IP interface
VLAN 1 IP was changed from default 192.168.1.254 to a static of 192.168.0.1.

I am going to get some wyse thin clients up and running on our departments. Each department communicate with the main-office through Cisco C1812 routers.
In order to get functionally DHCP up and running, I need to
A - Configure some Dhcp options on the C1812 routers
B - Perform a DHCP relay from each department to the main-office
Option B will cause some additional issues, so is not preferred.
The question is: Does the Cisco DHCP-client have an option for configuring DHCP options? I need to put in among others, an option 161, a string value pointing to a ftp-server. Can this be done? And if it can, what is the right syntax
I have recently started working here, therefore I am not certain of the IOS-version on the router, as I still not have the logon-information, but I will aqquire this shortly.

I upgraded my SG500 switch firmware to 1.3.0.59, since there is a new functionality DHCP server v.4 well I must say I came accross the issue I cannot solve. DHCP server assign dynamic address - no hassles. troubles start with static IP hosts.I defined a couple of hosts with static address within the correct subnet. I tried with hardware address and client identifiers. no luck. my switch does not assign the IP address I assigned to the suitable mac address. to define it I use both CLI & Web.

I have configured DHCP snooping on a WS-3560G-48PS running IOS 12.2(58)SE2 ipservicesk9 variant.When I enable DHCP snooping clients don't get IP addresses, when DHCP snooping is disabled, everything works fine.I have set up a SPAN port and run a capture (attached) on the traffic. Wireshark notes the Seconds elapsed field appeared to be encoded in little-endian but only on some packets. Apart from that, I can see nothing wrong with the DHCP Offer responses from my DHCP server.Attachment config.txt contains the interesting parts of the configuration. Please note g0/32 has been set to ARP inspection trust as without working DHCP snooping it would require a static bind.Is there any way of figuring out which option can't be parsed? Is there a way to force forwarding of unparsable DHCP packets while still running DHCP snooping?

I have 2 Catalyst 2960S (24 ports and 48 ports). Can I stack them using the Uplink connection instead of the stack modules. I know Stack module is the best option but it is kind of expensives (half price of the 24 ports switch) and I only need to stack no more then 2 switches.
