Oct 30, 2011I'm going to replace a Cat6513 with a Nexus 7018. In my Cat6513, there are object tracking config as follows:
ip sla monitor 1
type echo protocol ipIcmpEcho 112.78.254.249

ip sla monitor schedule 1 life forever start-time now
ip route 172.17.7.0 255.255.255.0 165.202.51.46 name VPN-1 track 123
Is there similar feature in Nexus platform? Because from Nx-OS command ref, I only found:
ip route ip-prefix/mask {[interface] next-hop} [preference] [tag id]
Seems can't associate a track object to a static route in Nx-OS?
Cisco Switching/Routing :: 5508 WLC And Nexus 7K - Clients Cannot Obtain IP Address Intermittently
Jan 22, 2013I have a strange behavior between a WLC 5508 (version 7.0.116.0) and NEXUS7010.
WLC
The WLC is configured in DHCP Bridging Mode (it sends DHCP requests without change)
Nexus
The VLAN interface is configured as follows
interface Vlan501
ip access-group acl-int-vlan501-in-1 in
no ip redirects
ip address 10.12.56.4/21
ip ospf network broadcast
ip router ospf 100 area 10.23.0.0
hsrp 51
Clients can not obtain an IP address intermittently. If I deactivates the ACL when the problem appears(when the client can not obtain an IP@) the probleme is resolved
Note: Before the WLC was connected to Catalyst 6500 and worked properly for 2 years (with same configuration)
I saw this note about differences between DHCP relay on the NEXUS7000/NXOS an Ip helper one the 6500/IOS URL. Do you think the problem may come from the DHCP relay or ACL on the NEXUS.
Cisco Switching/Routing :: 7018 Is VPC Peer-switch Command Intrusive
Apr 3, 2012I need to enable vPC "peer-switch" command on a pair of Nexus 7018s which are currently vPC peers (primary and secondary). The STP root and Secondary root are currently configured across these switches.Can I enable the peer-switch command in this configuration without impacting services, and then modify both switches to have the same bridge priority without impacting services ? We have a few downstream 5ks which are not dual homed to both vPC peers (work in progress) so need to understand if the peer-switch command will in any way break this connectivity for now.

View 2 Replies View RelatedCisco Switching/Routing :: Nexus 5000 LAN Routing Connection Deployment
May 16, 2013We have our Nexus as our default gateway (101.1) and the default VLAN1 is setup with two subnets 101.X and 102.X. The DHCP server is using a superscope setup to accomodate the overflow of devices requesting IPs on 101, so when 101 is consumed persons are able to obtain a 102.X IP address. The setup is basic on superscope. The issue is some times the routing to the firewall with a 102.X is not always 100%. Somedays all goes well and the 102 subnet is routed out to the firewall and its a good day. However, such as today a 102.X address is not routing as it did 24 hours ago. I am perplexed as to why this is behaving unpredicatable. Here is running-config for VLAN1 to show the 102 as secondary address to VLAN1.

Feb 16, 2011you find attached my network architecture with 2 Nexus 7010 on core layer and 2 Nexus 5020 on distribution layer, each one with 1 N2148T fabric extender switch. PC-A1 and PC-A2 are connected to one N2148T, PC-B1 is connected to the other N2148T. Nexus-7000-1 is HSRP Active for all VLANs, Nexus-7000-2 is HSRP standby. PC-A1 and PC-A2 are connected to VLAN A, PC-B1 is connected to VLAN B. PC-A1 and PC-A2 have the same default gateway correspondent to IP HSRP on VLAN A. It happens that PC-A1 is able to ping PC-B1 while PC-A2 is unable to ping PC-B1. If I issue a traceroute from PC-A2 I see Nexus-7000-2’s physical IP address as the first hop even if Nexus-7000-2 is HSRP standby. After the first hop the traceroute is lost. If I shutdown Port-channel 20 on Nexus-5000-2, PC-A2 starts to ping PC-B1.I can’t understand what’s wrong in this architecture.

Mar 25, 2012I have an environment where i have two nexus 7010 switches, along with 2 nexus 5510's. I need to run OSPF as a layer 3 routing protocol between the vpc peer links. I have 1 link being used as a keep alive link, and 3 other links being used as a VpC link.
1) Is it best to configure a separate Vpc VLAN i.e 1010
2) Is it best to configure a vrf context keep-alive
3) just have the management address as the peer ip's.
Cisco Switching/Routing :: Nexus 5548P Routing
Feb 6, 2012I have a pair of 5548P switches with the L3 daughter cards installed. Using the base license as I just need RIP routing. I have the two switches setup and have the RIP routing feature enabled. When I "turn on" routing using RIP I do not get any routes from my existing L3 switch (3750). I probably don't have routing setup correctly. With the 3750 IOS, I just turned on RIP with the router rip command and added a couple of network statements. On the nexus I have run router rip {instance} and left it at that. I am not getting any routes from my 3750. The 5548s are using the management ports and are connected to my existing network with L2 trunks. Does any know of a setup guide for RIP? I have used the Nexus 7000 RIP guide but still can't get it to work.

I have replaced the fan from another operational Nexus5K, and the fans are fine in the other Nexus. The replacement fans also have the same issues, so it is not a fan hardware issue.
There are no threshold alarms. the only log entry that is related to this is as follows:

Cisco Switching/Routing :: Per-VLAN QoS On Nexus 5K?
Feb 22, 2012I was reading a QoS walkthrough earlier to try to solve my problem and I noticed that in IOS, you can specify "match vlan" in a class map. This is not available in NX-OS. I'm not doing any routing on the 5K so I cannot match on ACL, and port where traffic is received is a trunk sharing other types of traffic I'd like to classify elsewise.
How can I match traffic on a per-VLAN basis?

Mar 11, 2012I'm having a little trouble setting up NTP on our new Nexus 3064s. We are using a local Meinberg M300 as our server and the Nexus 3064 as a client. Before I submitted a TAC I was wondering if the community would mind double checking what I have. One major issue I've come across is that the Nexus 3064 will only take a 8 character NTP passphrase. We normally use a 32 char MD5 string. I setup a new 8 char passphrase on our Meinberg M300. I am not using fabric extenders or distribution to other Nexuses. I am using an interface vlan as our management interface per our current network setup. I am using a VRF. We use some public IPs so all IPs are xxx'ed out. [code]
