I want to find the physical interfaces on the switch that these storage devices are connected to. I found the following two links, which may be helpful. I tried this to fix the problem and get my mac address to it's original state. The aim was to identify if anything wrong on core 2 related to dhcp relay 2. Or to put it a 100% correct, it should only be learned on one vpc at the same time.
Much thanks to everyone who responded! Each partition has only one default route-domain. A layer 3 switch only needs to resolve a host address if it is directly connected. I am curious to what you see as the benefit of waiting 30 1800 seconds minutes instead of the usual 5 300 seconds? Sometimes the problem manifests itself when the peer-link is brought back up rather than taken down. I moved to the next switch, repeated the whole process, moved to the third, ran the procedure again, moved on yet again … sigh. One maintenance window later, problem solved.
It doesn't show the synchronize option? Does anybody have any ideas what the issue might be? My problem is finally fixed! We have nexus 7000, there are multiple vlans But I am unable to ping from 10. Thank you for the responses thus far. With this value I can't get 2 full bgp - that is around 850K. Yeah, yeah, we know: the network is assumed guilty until proven innocent. In the current setup we have external dhcp server and dhcp relay is configured for all the vlans on Master and standby switch. Just want to make sure I'm understanding this 100% correctly. I did not find a layout like this in the manuals.
I have been fighting with the menu and the gui for a while now and do not see this anywhere. I have opened a support case with F5 and we have yet to determine where the issue lies. Now that we know what is already configured, what else should we configure, and why? Then go through and label all your port channel interface descriptions with what switch they connect to so you can save yourself some time next time. Below is troubleshooting I have tried. But prior to upgrading from 4. I've factory reset and flashed stock firmware several times without success. It should not be used publicly.
This topic has been discussed at length, please use the search feature. Kind of cumbersome, but still doable. The current behavior on earlier code pre - 6. We disabled the dhcp feature in core2 and enabled again with dhcp relay again configured on vlan interfaces. Thanks for the input - stevenmoores There will be multiple switches being reconfigured which already have populated mac tables.
Issue observed: It has been observed that new users were not getting ip address from the dhcp server. For all the vlans core1 is Master and Core2 is standby. Rule 5: No Early Career Advice. You could test that by entering the octets in reverse order, I guess - no promises though. We ran into a similar issue.
But when I enter the command Cisco config mac-address-table? You can use these commands on Cisco Nexus 7K in order to get the appropriate results from the chassis. Yep, you're on to the right start. Enterprise Networking Routers, Switches, Firewalls and other Data Networking infrastructure discussions welcomed. We are also connecting to Nexus switches using vpc albeit N5Ks as spines, being cross-connected via N7Ks as hubs and we are also using vcmp on Viprion though, not 5250. This is verbatim from Cisco documentation. It's a known issue with the 5548's. This is where things get a little tricky.
What I needed was a layer 2 traceroute tool. Performance of the network is good, there are no errors on any interfaces and I do not see anything related in the switch loggs. I have started ping to a server connected to a Nexus 5000 from a host that also conected to Nexus 5000. It's expecting certain traffic to come over a certain link vs. I am not a big fan of the web gui and was hoping to see the standard Cisco command prompt instead of the menu-type interface. Failover for the virtual servers is instant. Sep 14, 2010 I've configured ip dhcp snooping on several vlans I want to monitor and the binding table doesn't seem to be building.
Check all these commands to get the desired output on your lab network. I have seen behavior with this, where vmware will have the nics teamed in a port group, But if the cisco switch is not setup as port channel the mac addresses can change from one interface to another. I cannot find one by myself. Otoh, if you're trying to keep your arp table clean, the reverse thing is maybe worth a shot. Hope that helps even though it's not really an answer. Because everything doesn't go down to a plug in card or an equivalent chip, I think that the hierarchy isn't completed until the final board is assembled for your phone.
Moreover, this appears to be sporadic in nature with some vpc peer-link failure attempts recreating the problem and some not. In order to ensure syslog message generation, enter these commands in conjunction with the previous command. 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. Feb 23, 2011 We are facing issue of continous packet discards On nexus4001L link int po2 to Nexus5020 switch. Is that what you're asking? We have not heard anything definitive back from support yet.
