Catalyst 2950 / ip dhcp-server

Hello,
who can explain the use of ip dhcp-server on Catalyst 2950?
cat2950-03(config)#ip dhcp-server ?
Hostname or A.B.C.D IP address or Name of DHCP server
The "Catalyst 2950 and 2955 Cisco IOS Commands":
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat2950/12122ea2/2950cr/2950cr.pdf
does not list that command.
Is it the same as "ip helper-address xxx.xxx.xxx.xxx" without forwarding the other protocols like dns, netbios, and so in or does it configure the ios dhcp-server ( that should not be included on cat2950 - as far as I know)
Greetings from Germany

Looks like it configures a remote DHCP server.
cat2950-03(config)#ip dhcp-server ?
Hostname or A.B.C.D IP address or Name of DHCP server
So, say you have a DHCP server address of 10.34.1.1, the command would be
cat2950-03(config)#ip dhcp-server 10.34.1.1
That way the hosts on the switch will now where to send the requests for an IP address. Kinda like a Gateway address.
Just my thoughts, Please rate if this helps

Catalyst 2950 - Radius

Is it possible of crypter the password radius-server on a catalyst 2950. (example: "radius-server key 7 toto")?

Tagging on to this discussion from another thread in the forum:
Actually the answer to this question is very highly release dependent. Earlier releases did not support it. Current releases do. I am not sure where the change is and believe it may be a 12.3 (or maybe even a 12.3T) enhancement. I have quite a few routers (most with TACACS and some with Radius) where the key is encrypted. When I started with those routers the key was not encrypted. At some point in doing a software version upgrade the keys for TACACS/Radius started being encrypted.
The encryption of the TACACS/Radius key is part of the service password encryption. The service has been enhanced several times to increase the number of keys that it protects. If you have service password encryption enabled (and in a live network I hope that you do) and have a release that supports the new enhancement your TACACS/Radius key will be encrypted automatically. If your version of IOS does not support it yet the key will not be encrypted.

DHCP on Cisco Catalyst 2950 Switch

Hello
I need to configure my cisco catalyst 2950 series switch in order to act as DHCP server for devices connected to its ports.
Please say me, how to do that ?
Thank you
Narek

Please find the sample DHCP configuration for one of the VLANs.
Interface Vlan1
description Cisco DHCP

A 24 hour lease is the default if left out and the netbios-name-server is WINS in the Windows world.
If you want to use DHCP server for other VLANs as well create similar DHCP pools and assign the DG to the corresponding VLAN interface IP.

RARP Server for Catalyst 2950 Switch

Is there a RARP Server capability for the Cisco Catalyst 2950 Switch? I know that Cisco Routers support an "ip rarp-server" command. Do Cisco Switches support RARP?

To the best of my knowledge, the RARP protocol is working with cisco 2950 switch and also it supports in most of the cisco products.

Catalyst 2950 switch

Hello,
I am using a catalyst 2950 switch and connecting machines which have the operating system as TRU64 UNIX 5.1B (HP make DS25 servers) and WINDOWS XP Professional. The WINDOWS machines are getting connected on the network ( I am able to PING each other), but the UNIX machines are not getting connected on the network. The port LED on the switch is normal (GREEN). The netstat -r command on the UNIX machine shows default as defgw (/etc/routes) and the IP of defgw is defined in the /etc/hosts file. But there is actually no such gateway.
Please help me to get the UNIX machines connected on the network.
Thank You very Much
Best Regards
S R Vijayan

I wonder if the Windows machines are configured to use DHCP? If they are configured for DHCP and there is a DHCP server that is reachable, then it explains why the Windows machines have reachability to each other. If there is not a DHCP server available then the Windows machines are probably taking addresses in 169.254 (which is the default for Windows when it can not acquire from DHCP). This would also explain the ability of Windows machines to communicate with each other. Can the original poster clarify what IP addresses the Windows machines are using?
Then the question becomes how are the Unix machines configured? Are they supposed to use DHCP? Is so is the DHCP server reachable? If not how is the interface on the Unix box configured?
I also think that the suggestion about verifying whether the switch is configured with more than one VLAN is an excellent suggestion.

Can I use DHCP snooping and IOS DHCP server on the same switch stack

Hello,
I am shortly going to be deploying a Cisco CallManager solution for a customer whose network comprises stacks of Catalyst 3850 switches.
There is no separate core/server farm switch so the CallManager servers, voice gateways and IP phones will all plug into the same stack and be in the same VLAN (not my choice!).
For security we want to enable DHCP snooping and were planning on using the IOS DHCP server on the Catalyst switch stack.
Will this work? - when I enable DHCP snooping in networks with separate access layer switches I set the uplinks to the core as trusted links.
I am not sure whether DHCP snooping will work in this case. Do I need to set the VLAN interface on the switch as trusted, is this even possible?
Unfortunately I do not have access to a layer 3 switch to test this at the moment.
Thanks

Nope. That's the issue.
They'll sync on a third device acting as a hotspot, but the device sending a signal is not "on" the network it creates so the airport is all by itself on that network. At least that is what it looks like to me. Anyone have another take on it? Seems pretty silly that an iPad can put out a wifi signal, an Airport Express can receive a wifi signal, and yet there is no simple way to get them to communicate under this particular condition.

SG 300-28: how to configure it as DHCP server.

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 infomation from Firewall to which L3 switch is connected.
Thank you,
S.

Hi Sreenath,
I guess when you try the GUI or CLI interface, you would have noticed there is no mention of DHCP server.
They both mention, as does the datahseet, DHCP relay;
http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps10898/data_sheet_c78-610061.html
Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2
Relay of DHCP traffic to DHCP server in different VLAN. Works with DHCP Option 82
The new SG300-28 switch or ordering p/n SRW2024-K9, does not incorporate a DHCP server, but relies on DHCP relay to get IP addresses allocated to PC's on seperate VLANs.
If you needed a DHCP server within a Layer 3 switch you would have to look at the traditional Catalyst 3XXX series switch for that functionality.
I guess this is not the answer you wanted to hear.
regards Dave

Ccum 9.1 as DHCP server

Hello,
In my lab I have Cisco Catalyst Express 500 POE switch and vmware workstation 10 with 2 virtual machines Windows 2008 R2 acting as dns server and CUCM 9.1 which is acting as DHCP server as well, both the virtual machines as briged to the physical network and able to ping each other and the host operating system as well. The switch is configured with 2 vlans namely DATA 20 AND VOICE 30 all the ports are added to both the Vlan. THE PROBLEM IS WHEN I PUT THE PC ON ANY OF THE PORT THE IP ADDRESS IS ACQUIRED BUT WHEN THE PHONE IS ATTACHED DIRECTLY TO THE SWITHC PORT IT DOESNT ACQUIRES THE IP ADDRESS.
Thanks

We have cisco 2950 switch. can we use it as dhcp server in our network if yes then how ?
Please give me all commands to make it DHCP server.

Hi Blue,
i completely i won't accept the rest of ppl. say that DHCP is not supported on Cisco 2950, infact i am running dhcp server on my cisco 2950T-24 for the past 10 months IOS ver 12.1-22.EA6
find the commands
ip dhcp excluded-address 10.1.1.51 10.1.1.60

Catalyst 2950 trouble

I have been trying to get a Catalyst 2950 switch to work for over a week now. I received the switches with no box or packaging and I was told that there were no previous setup attempts on it. I tried performing the express setup but the lights on the server don't seem to behave the way the instructions explain. I also was never able to make a connection between the linux server I am trying to use to configure the switch and the switch. All i received was the switch and nothing else. I have an AC power cord and I also found an RJ45 - DB 9 adapter if needed. I have looked through alot of the manuals on the cisco main pages and nothing seems to be working or clicking. Please help!

Results of pinging from switch to linux box and switch to switch were both 0%.

Can I use ASA to be a DHCP Server use in WLC wireless Client

I want to use ASA to be a DHCP Server for Wireless Client not it can't.
I check the debug log in WLC, I confirm the WLC have send the request to ASA.
In the ASA, it don't have any hits in the rule when the WLC send the DHCP relay request.
I have try don't use dhcp relay in WLC but don't success. Anybody have the same case with me? And Is the ASA can't support DHCP relay agent to request to get the IP Addr.
P.S. In the Network Design limitation so I can't use WLC to be DHCP Server.
Equipment:
ASA5510
WLC4402
How can I fix it.
Thank you very much

The issue is that the ASA doesn't accept DHCP requests from a relay agent, only broadcast DHCP requests. In the 4.2 version for the controllers there is now an option so you can change the way the controller forwards DHCP requests so that it is sent as a broadcast and not from a relay agent.

For RADIUS you need a aaa-server-definition:
aaa-server NPS-RADIUS protocol radius
aaa-server NPS-RADIUS (inside) host 10.10.18.12
key *****
authentication-port 1812
accounting-port 1813
and tell your tunnel-group to ask that server:
tunnel-group VPN general-attributes
authentication-server-group NPS-RADIUS LOCAL

Can you use the Airport Express A1264 as an AP and a DHCP server at the same time?

Can you use the Airport Express A1264 as an Access Point and a DHCP server at the same time?
I would like to use it as a DHCP server and AP at the same time in my LAN (no internet, just local machines through a few switches). I was lead to belive this could be the case from a few networking friends that haven't been friendly enough to help me out setting it up.

I need it to act as a dLink/Cisco/Linksys/etc basic wifi router, in the fact that you can access it via wifi, and it will spit out DHCP addresses (192.168.1.xxx) to everything wired downstream of it.
I want to simultaniously provide a Wifi connection and a LAN connection at the same time
Thanks,
BRad

Can I use my WRT54G as a DHCP server only? I've got 5 dynamic IP's from Time Warner..

Hi everyone, I'm wondering if I can use my WRT54G as a DHCP server only only my network, without having to have any of my PC's plugged into it's router ports? I looked at the settings but I couldn't get it to work.
Here's why: I just got Time Warner Business Class cable internet which comes with 5 dynamic IP's. I want each computer, well 4 of them at least and 1 for the WRT54G, to have a unique IP when accessing the internet, and the other computers (5 more computers) to use the DHCP server in the WRT54G to get a NAT IP for use on the internet.
We play Diablo II on the internet and only 4 computers can be connected through 1 IP, so that limits us in my current configuration.
Current Equipment: One WRT54G, one Netgear GS116 16 port gigabit non-managed switch. One Time Warner Cable modem. Also attached to the network is one HP network printer, a Buffalo LinkStation NAS and a Zensonic Network DVD player.
Current config: Cable modem --> WRT54G --> Netgear switch.
Ideal config: Cable modem --> Netgear switch --> WRT54G.
With my current config, I am not taking advantage of the 5 dynamic IP's, but all the computers connected to the Netgear switch or the WRT54G can connect to the internet and the NAS.
So my ideal config (where I don't have to buy anything and where all the computers can print and access the NAS) is to connect all the computers and devices to the Netgear Switch and somehow force 4 of the computers and the WRT54G to get a dynamic IP from the cable modem, while the other computers and devices use the DHCP server on the WRT54G to get to the internet.
Is this possible?
I called Time Warner Cable and they weren't any help. I called the Linksys sales department and they weren't of much help either.
I suppose that I could purchase a new 8 port switch and attach 4 computers, the cable modem and the WRT54G to it. Then attach the Netgear to the WRT54G to accomodate the printer, NAS, and the other 5 computers. But in that senario, the 4 computers connected to the new switch can't print and can't reach the NAS. And geez, some computers would have to go through 3 devices to reach the internet, which has got to slow them down.
I did read about the Linksys EFG120 which has a DHCP server, but at $400 and only 120 gigs, it doesn't work for me.
I called Time Warner and the cost of more dynamic IP's is prohibitive, I'm already paying $79 a month for this internet and they want another $50 a month for 7 more dynamic IP's and that wouldn't help my NAS or my printer.
The cost of a 16 port gigabit switch with DHCP is an amazing $800 or so, which is out of the question.
Sorry for being so long winded and thanks for reading this far. I'm looking forward to any replies.

That is a hell of a setup. I don't know if it would be easier and cheaper to either buy a real router like a Cisco, get fixed IP addresses and a RV042, or buy 4 network cards for the four of the five computers which need the internet access for gaming.
O.K. First your setup:
1. You wire the modem to the 6-port switch.
2. You connect the remaining 5 ports with the WAN ports of 5 WRTs with DHCP on the WAN interface.
3. You configure each WRT with unique LAN IP addresses in the same subnet, e.g. 192.168.1.1/255.255.255.0, 192.168.1.2, 192.168.1.3, 192.168.1.4, 192.168.1.5.
4. You turn off all DHCP servers except on one, e.g. 192.168.1.1. That router will be the default router and internet connection for any client which gets dynamic LAN addresses (as fallback or guests, I would not configure the NAS or printer with DHCP addresses if you have everything else on static IP addresses). You can certainly disable all DHCP servers if you want, too.
5. Now you connect all WRTs with each other.
5a. You connect port 1 of the 1st WRT with port 1 of the 2nd.
You connect port 2 of the 2nd with port 1 of the 3rd.
Port 2 of the 3rd with port 1 of the 4th.
Port 2 of the 4th with port 1 of the 5th.
(Do not create a loop connecting port 2 of the 5th with port 2 of the 1st!!)
5b. You buy another switch and connect each port 1 of each router with this switch. This has the advantage that you don't have a long cascade between the 1st and the 5th router like in 5a.
6. You connect all devices to the LAN.
6a. If you did 5a, you will probably put each computer to the router which internet connection it uses. The NAS and printer could go anywhere.
6b. If you did 5b, you hopefully bought a 16 or 24 port switch. Then you plug simply everything into that switch. Otherwise you can certainly use the free ports of the WRTs like in 6a.
7. You configure all your devices with static IP addresses. For instance,
IP 192.168.1.11
netmask 255.255.255.0
gateway 192.168.1.1
For the DNS servers I would highly recommend to use the DNS servers of your ISP directly and not use the relay on 192.168.1.1.
The gateway address defines through which router the computer connects to the internet.
8. You may still have to configure port forwardings on the router to the game computer if required for the game.
An interesting alternative to this setup might be to buy 4/5 network cards for the 4/5 computers with direct internet access. Then you use the one network card to connect to your single LAN behind your single WRT. The other network card goes into the switch behind the modem and has direct internet access. You then have to tell Windows which of the network cards has the default gateway for the internet connection (to prevent routing all traffic through the LAN and the WRT to the internet). One game computer would have to be behind the WRT.
