Cisco Switching/Routing :: Does Ip Helper Address Work On A Layer 2 Switch 2950
Jan 9, 2012I would like to know if ip helper-address feature is working on a layer 2 switch (2950,2960) or you should use a Layer 3 switch to do that?

May 25, 2012I 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 Routers :: RV220W Built-in DHCP Server Can't Save Class B IP Address Pool
Mar 28, 2012I was trying to set a DHCP pool with 127.16.0.0/16 with RV220W, however, RV220W UI can't save it. It displays "IP Address Range -"Step to reproduce: (it is 100% reproducible)
1. login into RV220W admin web
2. Create a VLAN, id 201
3. Go to "Multiple VLAN subnets", select the VLAN, click edit
4. Enter following info:
IP Address: 172.16.0.1
Subnet Mask: 255.255.0.0
DHCP Mode: DHCP Server
Domain Name: Cisco
Starting IP Address: 172.16.2.100
Ending IP Address: 172.16.10.254
Primary DNS Server: 172.16.0.1
Leave rest of settings with default value.
DNS proxy is enabled
5. Press Save button. The UI shows text "IP Address Range -".
Expected result: RV220W shall save the setting and make use of 172.16.0.0 subnet in IP pool. By the way, the error message "IP Address Range -" seems incompleteI tried same setting on netgear FVS318N (very similar settings to RV220W), it accepts 172.16.0.0/16 as DHCP IP pool and works.RV220W has great feature set meets my needs. Its UI is slow and sometime dashboard freezes, which I can live with comparing to features. But DHCP server IP pool can't be class B is huge limitation to me.

Apr 3, 2012Have a client wanting to hand out public ip addresses to all clients from a PFSense Firewall terminating the internet connection.
How do I allow the Cisco Switches currently in place, configured with private ip addresses in the 10.10.x.x ranges and Vlans, where the main 3550 layer 3 has defined dhcp scopes for each vlan, to relay dhcp requests from all vlans to the PFSense firewall?
I assume I would take off the currently defined dhcp scopes for the vlans and configure each vlan/switch with the ip helper address and specify the PFSense firewall and that Nat would have to be disabled onthe firewall?

Cisco Switching/Routing :: 3911 Router DHCP Server Not Giving IP Address
Jan 30, 2011I have a 3911 router with a 1242 AP. The problem that I have is that when the user is trying to connect, the user get the OS Ip address 169.254.168.154 and I see that when I do the "show dot11 association" command, but when I do sh ip dhcp binding on the router I see
172.19.9.141 0100.18de.74db.14 Jan 31 2011 11:14 AM Automatic
The router is seeing as if the router gave the ip address to the user, but the reality the user was assigne the OS ip address 169. I did "debug ip dhcp server events" and I got the following:
Jan 31 11:09:06.752 EST: DHCPD: Seeing if there is an internally specified pool class:Jan 31 11:09:06.756 EST: DHCPD: htype 1 chaddr 0100.18de.74db.14

Cisco Switching/Routing :: Nexus 7010 New Users Were Not Getting Ip Address From Dhcp Server
Jun 8, 2013We have 2 nexus 7010 switches configured with HSRP in the network. For all the vlans core1 is Master and Core2 is standby. In the current setup we have external dhcp server and dhcp relay is configured for all the vlans on Master and standby switch. The setup is running the IOS 5.2
Activity Done: During the Maintainacne activity, we isolated core1 switch in the network by disabling the vpc/keepalive and all the uplinks from access switch. The core2 switch was master for all the vlans.
Issue observed: It has been observed that new users were not getting ip address from the dhcp server. The ethereal capture showed that dhcp server was not getting the dhcp requests from the core2 switch. We disabled the dhcp feature in core2 and enabled again with dhcp relay again configured on vlan interfaces .even after doing this no change was observed in behaviour. Finally we got core1 back in network by enabling all the links.
Observation: The moment VPC link came up between the core switches, users started getting ip's from dhcp. Then we started enabling all the uplinks on core1.Core1 again become master for all the vlans and users continued getting ip’s. Network running fine.
Further Testing
1. For one of the vlan, core 2 switch has been made primary and for new users checked the dhcp functionality and it was working fine. The aim was to identify if anything wrong on core 2 related to dhcp relay
2.Again we changed the priority for this vlan and made core1 master for the same. This time we disabled this vlan on core1 and tried new user with core 2 became master and dhcp functionality worked fine for new user. Actually in this case we have simulated the same behaviour when we observed the issue with only difference of VPC was not available during the issue time as core 1 was isolated form network
Inputs needed.
Is there any known behaviour for dhcp functionality when VPC is unavailable? If we see the test scenario2 (wherein core1 was master for the vlan and we disable this vlan on core 1 and core 2 was able to relay dhcp requests for new users in this vlan.) it was actually same as scenario we observed during issue time..
