Cisco Switching/Routing :: Port / MAC Based DHCP For 2960 And 3560

Jan 3, 2012

I want to implement port-based and MAC-based in these two switches: 2960 & 3560 (both of them have this IOS version: 12.2(55)SE1). And I haven't found a way to implement both of them at the same time. This is what I got:
ip dhcp use subscriber-id client-id
ip dhcp subscriber-id interface-name
ip dhcp excluded-address
ip dhcp excluded-address

With this configuration I can use port-based, but not MAC based. If I remove the first two lines and change the last line for this one:

address client-id 0112.ae1d.af58.60

Then, the computer with that MAC address got the correct IP, but then the port-based doesn't work. Also, I got this line in the interface what I want to use MAC-based: 

ip dhcp server use subscriber-id client-id

Cisco Switching/Routing :: P3750-E - Port Based DHCP IOS 15 Not Working

Apr 9, 2013

I am upgrading from 3750-E IOS 12.2 to 3750-X IOS 15.0
I have a dhcp pool set up to give out an ip address based on the Physical port of the switch.  I also have it configured to give out "reserved only" addresses.
The configuration works when i plug a dhcp device in the 3750E. (IOS12.2) The configuration does not work when i use the same config on 3750X (IOS15)                  
When i debug dhcp, i see the DHCP discover message come in, but no offers or anykind of response from the 3750X.
If i remove the "reserved only" line the switch gives out IPs, but of ocurse not the ones i want.  I did that to prove both the client and the switch can give out an IP.
So i have a feeling the subscriber-id client-id interface name  mapping is not right, or not created.
Here is a snippet of config.
no ip dhcp use vrf connected
ip dhcp use subscriber-id client-id
ip dhcp subscriber-id interface-name

Cisco Switching/Routing :: Make Policy Based Routing On 3560?

Apr 17, 2012

I have tried to make policy based routing on Cisco 3560. I use ipservices ios (SW version 12.2.(50)SE3 and SW-IMAGE C3560-IPSERVICESK9-M)  For below configuration there is no problem and pbr is working.
“Access-list 100 permit ip host host
Access-list 101 permit ip host host
 Route-map pbr1  permit 10
Match ip address  100
Set ip next-hop verify-availability 1 track 11
 interface fasthethernet  0/1
ip policy route-map  pbr1”
But when i add another sequence to the "pbr1" with another sequence number  like that.
“Route-map pbr1 permit  11
Match ip address  101
Set ip next-hop verify-availability 1 track 12”
pbr is not working. Switch gives message "PLATFORM_PBR-3-UNSUPPORTTED_RMP:Route-map pbr1 not supported for Policy Based  Routing”"ip policy route-map pbr1" command not shown in the running config. And "show ip policy" output is blank.Configuration guide says you have insert many sequence to the route-map with the same name. And also this command is not in the unsupported command list.

Cisco Switching/Routing :: Catalyst 3560 / 2960 Web-user Management

Jun 7, 2011

We have quite a few 3560 & 2960 on our edge network - what I have been looking at was to access switches via web-interface i.e. web-browser. Only problem with this is it always gives you access on privilige level 15 which is not ideal as not all who we decide to give access to these switches will be admin and allowed to configure these swicthes - In the 3560/2960 data-sheet states:
"Alternatively, a local username and password database can be configured on the switch itself. Fifteen levels of authorization on the switch console and two levels on the Web-based management interface provide the ability to give different levels of configuration capabilities to different administrators"
Where as there is no mention of how to configure these two levels of Web-based management in the configuration guide.

Cisco Switching/Routing :: 3560 / 2960 - Potential Spanning Tree Method

Oct 16, 2011

I have a Cisco 3560 running as a Level3 device in my network running 10 V LANs and routing between most of them (nothing complex with ACLs) and running spanning-tree mode pvst. The main network is run on a net gear GS748TPS stack of three switches running MSTP.
I have just bought an additional 3560 and a 2960 to plug in. I have set them up with IP addresses and then plugged them into the net gear. This brought the whole network down until I unplugged the new switches.
I have confirmed the IP addresses aren't duplicated and that DHCP is not running on the switches so I can only assume it's something to do with DHCP. I cannot afford for the network to go offline again, so is there anything I should check? Am I running incompatible spanning tree methods between the net gear and Cisco devices?

Cisco Switching / Routing :: 3560 - Management Port Used As Regular Port?

Jan 30, 2012

I have an all gigE  3560.  I don't use the management FE0 port on the back.  I was thinking to use that for a 100Mbps WAN connection. 

Seems to work just fine when I plugged in an test.  But I am not routing across that link yet as I still need to setup the far end.

Is there any reason this would not work?  I would like to not burn a gig port if the max throughput of the circuit is 100Mbps.

Cisco Switching/Routing :: 3560 Implement DHCP Snooping

Oct 12, 2011

I have attempted to implement DHCP snooping and have been having some strange issues. I have 5 3560s taht I use for my edge and when I attempt to implement on all five, the VLAN that houses my voice data appears to no longer be able to recieve DHCP lease renewals so after the 24 expiration all of my phones lose their configs. Once I roll back the changes the voice VLAN comes back. The other VLANs seem to function correctly as theya re able to renew their DHCP addresses.
The 3560s tie into each other using GIG Ports 1 & 2 and the top and bottom switches tie into our core switch, a 4507. The config that I use is below, failry simple and straightforward.

4 of the 5 switches feed our general office vlans for voice and data however the 5th switch is there for expansion and not in use. As such I have left the config changes in place on it and have tied myself and a colleague into it and have been operating fine for over a week now. So the config that I use seems sound in theory and should work on the other 4 switches with no issue.

Cisco Switching/Routing :: 3560 DHCP In Layer 3 Switch

May 25, 2012

I have made a topology by using one 3560 switch and 2 2950 switches. I have also made 2 vlans name Clients and other Servers and vlan 1 is for anagement purposes. The left 2950 switch is for clients and the right is for servers. Clients is vlan 2 and servers is vlan3 . Now what i want is that my dhcp is should assign ips to clients in vlans 2 provided that servers are in vlan 3. I am also using a border router and i have introduced a default route on the 3560 to the border router.
Now when i assign static ips to my clients pc and server dhcp then i can ping between vlans but when i try to assign ip through dhcp then it wont work. Also the default route on the switch to the border router doesnt seem to work. I can ping only the border router when i put a default route on the border router instead of the 3560 switch.

Cisco Switching/Routing :: 3560 DHCP Between Switch And Router

Jul 23, 2012

I have a cisco 3560 24PS and its connected to two ADSL broard band is a personal broadband line using a Billion ADSL broadband router, and the other is a business broardband line using BT's 2wire broadband line.on the Billion routers i have various things attached like a NAS and a printers, both wired connections. then i have laptops and phones that connect over wifi, so its configured to act as a DHCP server
the only thing conncted to my 2wire router is my company's laptop (wired or wifi depending on where i'm working from), so again i have it working as a dhcp server.The switch is configured with multiple vlans, with dhcp scopes assigned for each vlan.I have a static route pointing all traffic to my Billion ADSL for internet connectivity.
The problem i'm having is that when i turn on the cisco switch, all wifi conected devices loose their conection. only 2 things get it working again, a reboot of the router, or disabling then enabling the DHCP service on the router.upon further analysis i was able to find out that the devices were not able to pick up an address from the router. again i looked deeper into this and i can see the following on logs of my router: [code]
so it seems that the router tuns off its DHCP capabilities because it detects that my Cisco switch is running DHCP services. I need to figure out how to keep the billion routers DHCP running when ever the switch is turned there a way of filtering out any DHCP chat from the switch to the router?

Cisco Switching/Routing :: 3560 - Basics Of DHCP Snooping

Jan 18, 2013

I am trying to understand the basics of DHCP snooping.  I have a just a 3560 switch and a laptop ( to get a DHCP address) and my DSL router which has a DHCP server running.  On the switch I have enabled "IP DHCP Snooping" and "IP DHCP Snooping VLAN 1" plugged the laptop and DSL router in and the laptop gets and IP address, should it? 

I thought all ports were untrusted by default so the DHCP server should be blocked at offering IP addresses? If I wanted the DHCP server to be allowed to offer IP's I thought I should need to trust the port.
