View 3 Replies View RelatedCisco 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..

Feb 20, 2013the phone connects to the 3750-A access layer switch (VTP mode client) which connects to the nexus 5596 (The nexus is the layer 3 device and set to vtp mode server) and finally we have a Voice recorder that connects to another access layer 3750-B switch.(VTP mode client)
For voice recording I need to setup RSPAN and the nexus5596 does not support RSPAN will the following have any impact on the nexus
IF I move the 3750-B to VTP server mode and run the command remote span on the VLan I need to Rspan its going to update the VTP data base in short it will update the vlan.dat file for all the switch in that VTP domain.
AS the vtp update reaches the nexus saying there is a change (keeping in mind the nexus does not support rspan not sure hows its going to handle that request and how its going to update its vlan.dat file)
Is it going to incremment the VTP revision number? can it crash the vlan.dat file on the nexus ? or do nothing and ignore the update and stop the update from proceeding to the 3750 A switch?
