Cisco Switching/Routing :: Nexus 3048 VPC Doesn't Form

Jun 11, 2012

I am building up vPC on 2 x Nexus 3048 and found that it did not work properly.The current config as follows,
 
1. OS: n3000-uk9.5.0.3.U2.2.bin

2. Peer link: 10 x 1G (E1/1 - E1/10) on both devices (I am wondering that 1G interface supports vPC Peer-Link. I heard that upgrading to U3.2 image will work for 1G rather than 10G... )

3. They can ping each other via management IPs

4. Edge switches vPC have not been built yet (I am focusing on Peer-Link and vPC role selection)

Cisco Switching/Routing :: Configuring VPC On The Nexus 3048

May 22, 2013

I'm looking for some input on configuring vPC on the Nexus 3048.I know that it's supported to use 1G interfaces for the vPC Peer-Link, but using 2x1G for the Peer-Link would make the Peer-Link a bottle-neck if the 10G ports are used in a vPC. What about using 2x10G ports for the Peer-Link and using the remaining 10G ports in one, or potentially two vPCs. Should that work or is it in any way not recommended? The reason I'm asking is that the 10G ports are called "Uplink" ports in the data sheets for the 3048.
 
We are planning to connect some servers to the 3048s using vPC with each server connected by 4x1G interface (2x1G for each switch), and then we want to connect a Netapp storage system with two controllers using 2x10G each (the controllers are active/passive, so you can think of it as two separate systems). We would connect controller A with vPC 1x10G to each switch, and controller B in the same way with vPC 1x10G to each switch.

I have been assigned the task of trunking VLAN between a Nexus 3048 and a Force10 S4810. This would seem easy enough but I am really having a bear of a time getting it to work. I have devices configured on VLAN 602 on both sides but they just are not talking.

Cisco Switching/Routing :: Nexus 7009 - Syslog Configuration Doesn't Seem To Work For NX-OS

Sep 10, 2012

we've been using IOS for a long time, but are relatively new to NX-OS. We've got a central syslog server that all our devices log to. No matter what we do, we can't get our Nexus switches to log there. Here's my current attempt:
 
Nexus 7009, NX-OS 6.0(1)
 
# sh logging server
Logging server:                 enabled
{redacted}
server severity:        debugging
server facility:        local7
server VRF:             default

[code].....
 
The default VRF is working. I see log entries in the logfile, but nothing arrives at the syslog server. It's not a config issue on the server, because tcpdump shows that no packets arrive from the IP for loopback 0.

we are planning a Nexus datacenter project with this layout:Our experiences with Nexus switches are not so large until now and the manuals are very extensive.Both N5K´s should be connected directly with all 4 N2K switches. I did not find a layout like this in the manuals. Only a design,where only 2 N2K are connected to one N5K, with this fex config:Now I´m not sure if it is right to make a config like this with the same slots and fex´s or with different slots and fex´s.

Cisco Switching/Routing :: Nexus 7010 / VSS - Does It Support Virtual Switching?

Does the nexus 7010 support virtual switching yet?  All of the posts I have found from about a year ago say that it is going to be supported, but there were no dates listed.  I heard the same thing from Cisco a while back, but haven't followed up with it.If it is supported finally are there any configuration guides available for it?

Cisco Switching/Routing :: Nexus 5000 LAN Routing Connection Deployment

May 16, 2013

We 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.

Cisco Switching/Routing :: Nexus 7010 - Inter-VLAN Routing On Multilayer VPC Environment

Feb 16, 2011

you 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.

Cisco Switching/Routing :: Nexus 7010 / 5510 - Run OSPF As Layer 3 Routing Protocol Between VPC Peer Links

Mar 25, 2012

I 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, 2012

I 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.

Cisco Switching/Routing :: Nexus 5k High Fan RPM

Jun 8, 2013

The fans 1 & 2 in Module 1 on the Nexus5K are still experiencing the very high RPM and speed issue.
 
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:
 
%NOHMS-2-NOHMS_ENV_ERR_FAN_SPEED: System minor alarm in fan tray 1: fan speed is out of range on fan 1. 7950 to 12500 rpm expected. I have provided the output for both the fan detail and the temperature.

Cisco Switching/Routing :: Per-VLAN QoS On Nexus 5K?

Feb 22, 2012

I 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?

Cisco Switching/Routing :: Vlan On Nexus 7K Is Down

Apr 17, 2013

I am working in my lab and I was adding a new L2/3 vlan

vlan 555
name test
 
int vlan 555
ip address 1.1.1.1/24
no shut
 
I have also ensured that this vlan is added to the port channel going to my Nexus5K's.  I added the vlan to the 5K's and also ensured that vlan 555 is traversing the peer link.  all is good there.  I have also placed a device on a interface on the 2k as a access switchport on vlan 555
 
Here is my problem, the L3 interface will NOT come up on the 7K
 
LAB-DSW01# sh ip int brie
IP Interface Status for VRF "default"(1)
Interface            IP Address      Interface Status
Vlan555             1.1.1.1     protocol-down/link-down/admin-up  
 
I have gone throug just about everything I can think of and I am still unable to get this L3 interface to come up.  I have other L3 interfaces on this device that are configured exactly the sameway without any issue at all.  All the existing interfaces are working properly, it's jut this new interface that I am trying to add.
 
I am running version 6.0.1 on the 7K and 5.2.1.N1.4 on the 5K.
