Config ethernet interface on Nexus 7010
Hi all,
Please help to config the ethernet interface port 1 on slot 7. The old 6500 command "interface 7/1" does not work, got message "invalid range". Thank you.
Also I have the 1/10 Gbps Ethernet module (N7K-F248XP-25E), please educate me how to choose between 1 or 10 Gbps for the end devices ? Thanks.
Wouldnt it be interface ethernet7/1 ?
interface Ethernet3/5 is a interface configured on my switch. It is a 7009

Port-channel L2 problem with Fabric Interconnect and Nexus 7010
Hi,
i using port-channel from both fabric interconnect to N7k with 3 cables per Fabric Interconnect.
but, my problem is when i creating port-channel, Fabric Interconnect don't support mode ON dan rate-mode share in Interface 10G Nexus 7010.
I was trying :
1. I using non dedicated port in Nexus 7010.
- rate-mode share
- channel-group 1 mode active
- switchport mode trunk
when i using this option, the port-channel in Nexus 7010 was suspended
2. I using non dedicated port in Nexus 7010
- rate-mode share
- channel group 1 mode on
- switchport mode trunk
when i using this option, the port-channel in Nexus 7010 was came up, but in Fabric interconnect was failed.
3. I using dedicated port in Nexus 7010
- rate-mode share
- channel group 1 mode active
- switchport mode trunk
when i using this option, the port-channel in Nexus 7010 was suspended
4. I using dedicated port in Nexus 7010
- rate-mode dedicated
- channel group 1 mode active
- switchport mode trunk
when i using this option, the port-channel in Nexus 7010 was came up and running well.
but, the problem is my costumer do not want using a dedicated rate-mode. if i using dedicated mode the only available port is 8 interfaces instead of 32 ports. i want to using rate-mode share in nexus 7010.
is there any way to configuring port-channel using mode on in fabric interconnect ? i was trying using CLI to create port-channel in Fabric interconect but i cannot configure the channel group protocol.
i attach the topology of N7K with Fabric interconnect.
regards,
Berwin HHi Manish,
the issue was solved, i was fix it last week.
the solution is:
i enable the license grace-priode (since my license is Enterprise so cannot create VDC) then i create a VDC (ex: VDC 2) so i allocate the interface on all module

N7K-M132XP-12 to VDC 2. after that i delete VDC 2 then all interface back to VDC 1 (default vdc). then i enable the rate-mode share in dedicated port and bundle into port-channel and its working.
i dont know why it must move to VDC first then it will working, maybe cisco can explain the reasons.
So here the result of my port-channel :

Nexus 5000 - Odd Ethernet interface behavior (link down inactive)
Hi Guys,
This would sound really trivial but it is very odd behavior.
- We have a server connected to a 2, Nexus 5000s (for resiliancy)
- When there is no config on the ethernet interfaces whatsoever, the ethernet interface is UP / UP, there is minimal amount of traffic on the link etc. E.g.
Ethernet1/16 is up

- This behavior is seen on both 5Ks
- I've tried using a different set of ports, changed SFPs, and fibre cabling to no avail
- I can't seem to understand this behavior?! In that, why would configuring the port cause the link to go down?
- If anyone has experience this before, or could shed some light on this behavior, it would be appreciated.

SheldonI had identical issue
Two interfaces on two different FEXes were INACTIVE. I have two Nexus 5596 in vPC and A/A FEXes.
I also use config-sync feature.
Very same configuration was applied to other ports on other FEXes and they were working with no problems.
interface Ethernet119/1/1
inherit port-profile PP-Exchange2003
I checked VLAN status associated with this profile and it was active (of course it was, other ports were ok).
I solved it by removing port profile from this port and re-applied it... voila, port changed state to up!
Very very strange. -
MGTM0 Interface only in Admin VDC in Nexus 7010
Hi guys,
I created two new VDCs in a Nexus 7010 (NX-OS 6.2.6) and I can see the MGTM0 interface only in the Admin VDC
I wanted to see the MGTM0 in all VDCs.
Does someone get this problem too ?
My Best Regards,
Andre Gustavo LomonacoHi Reza,
Thanks for your reply.
If the user run the setup wizard, the interface mgtm0 will be created in VDC.
If the user don't run the setup wizard, the interface mgtm0 will not be created and you will need
to only use the interface mgtm 0 command to create the interface.
Thanks a lot -
How to config management interface to an ethernet interface?
we have an ASA 5540 that require LAN port for failover. And the only available interface left is the management port. How to config management interface to an ethernet interface?
You can disable the management-only mode on that interface to make it as regualr routable port and use for any other purpose including LAN base failover purposes.
About management interface - 5510 but generally applies to management0/0 itself including 5540

Nexus 7010 Loses Config after power off
Recently we installed a pair of Nexus 7010's and we recently moved them to an APC rack better suited for their size. Upon powering them up we found out that the VDC's lost their configurations. The VDC's and the alloated resources were still there as well as the default VDC configuration but the other 2 we have configured had their configurations missing. We have been observing best practices and saving the configuration to NVRAM with the copy run start comand as well as the copy run start vdc-all commands yet the configurations were still lost.
Can anyone shed some light on what the problem may be?
Thank you in advance for your help!We had the same issue TAC told us to reset the supv
,,,,, you might want to save your config ;-) it worked for us -

Hi all.
The problem.
Today I updated my Nexus 7010 sup1 from 6.1.4a to 6.2.8.
I want did it in ISSU mode, but after impact check I got this:
Compatibility check is done:
Module bootable Impact Install-type Reason
1 yes non-disruptive rolling
2 yes non-disruptive rolling
3 yes non-disruptive rolling
4 yes non-disruptive rolling
5 yes disruptive reset Some LACP ports not in steady state or operating in 'rate fast' mode.
6 yes disruptive reset Some LACP ports not in steady state or operating in 'rate fast' mode.
7 yes non-disruptive rolling
8 yes non-disruptive rolling
9 yes non-disruptive rolling
10 yes non-disruptive rolling
Additional info for this installation:
Service "lacp" in vdc 1: LACP: Upgrade will be disruptive as 6 switch ports and 0 fex ports are not upgrade ready!!
Issue the "show lacp issu-impact" cli for more details.
(modified the impact to <Hitful> for module <6>)
Do you want to continue with the installation (y/n)? [n] y
I went on with yes and update script reboot both sups after updated all modules.
It was quite a surprise for me (yes I know I must see word "disruptive" opposite my sups 5 and 6). Because I already had done two ISSU updates on two nexuses (from 5.1.* ->5.2.7 and 5.2.7 -> 6.1.4a) and didn`t have any trouble with LACP timers. Is it a new feature of the 6.* train?
I have another Nexus that I want to update. And it also has same problem with LACP timers.
show install all impact give me the same disruptive result because of LACP.
Can I somehow suppress such ISSU behavior? In case of LACP. I don`t have vPC, just ordinal PC.
It is a way better if some LACP interfaces flap in process, than an almost 14 minutes of all 7010 chassis reboot that I had.
Although problem with LACP timers is that they must be the same on the switch side and on the other side. And in case of switches, linux boxes or HP VCs changing LACP timers isn`t a big problem. IT is a biggg problem in case of the Windows Server.
sh lacp interface ethernet 8/13

They must be the same and equal 30s for successful ISSUYou probably need to dig a little deeper to get a definitive answer (sup1 or 2, type of cards, etc..) but here is a diagram in the release notes for 6.1 found here:

Nexus 7010 - redistribute host routes in to OSPF
In my Nexus 7010 infrastructure, I have a requirement to redistribute host routes in to OSPF so that the other connected sites receive the host routes through OSPF.
These hosts are part of the connected network (192.168.100.0/24) on Nexus, I dont want this network to be advertised in to OSPF but I want the hosts inside this subnet (192.168.100.11 and 192.168.100.12) to be advertised.
I tried to create a prefix list with these two hosts and added them to a route-map and then using the "redistribute direct" command called this route-map in to OSPF, but this is not working.
However, if I add the entire subnet (the connected network) in to this route-map, it shows up in OSPF.
Is there a way I could have only the hosts to be part of the OSPF database?Hello, There is no need for VDC or VRF I think. are we missing a trick here. I also just tested for my own sanity. (Or am I completely under-thinking this)
N7K-1 has vlan 24 and the host route will be to 172.25.24.20
N7K-1 Config:
conf t
ip route 172.25.24.20/32 Vlan24
ip prefix-list TEST seq 5 permit 172.25.24.20/32
route-map STATIC_TO_OSPF permit 10
match ip address prefix-list TEST
router ospf 1
bfd
router-id 192.168.101.1
redistribute static route-map STATIC_TO_OSPF
here is what I see on its neighbour N7K2:
DC1-N7K2# show ip route 172.25.24.20
IP Route Table for VRF "default"
'*' denotes best ucast next-hop
'**' denotes best mcast next-hop
'[x/y]' denotes [preference/metric]
'%<string>' in via output denotes VRF <string>
172.25.24.20/32, ubest/mbest: 1/0
*via 192.168.102.5, Eth8/1, [110/20], 00:00:07, ospf-1, type-2
DC1-N7K2#
Type-5 AS External Link States
Link ID ADV Router Age Seq# Checksum Tag
172.25.24.20 192.168.101.1 479 0x80000002 0x0eed 0
So in essence point the host routes statically to the directly connected interface.

Thanks
PatrícioHi Particio,
The port-channel/vPC features require that all uplinks are connected to the same type of
module. You can refer to the following document.

Nexus 7010 fabric extender timing out
Hello -
We have a Nexus 7010 and we are testing out using the fabric extenders for a need. We have a demo 2224 unit and have it connected to our M132XP-12 10G blade in the 7K but the FEX won't come online.

This is what the status shows after it spends about 15 mins in the image download state.

Question about Nexus 7010.
Hello everybody,
Just a quick question, how do you restore a running-config (or a Nexus .bin file) to a Nexus 7010. Is it thesame process as the IOS base scenario. Please explain and help. Thank you in advance.
--chieCopy tftp: running-config should work. See below there are other options as well.
NX7K02-agg# copy ?
bootflash: Select source filesystem
core: Select source filesystem
debug: Select source filesystem
ftp: Select source filesystem
log: Select source filesystem
logflash: Select source filesystem
nvram: Select source filesystem
running-config Copy running configuration to destination
scp: Select source filesystem
sftp: Select source filesystem
slot0: Select source filesystem
startup-config Copy startup configuration to destination
system: Select source filesystem
tftp: Select source filesystem
usb1: Select source filesystem
usb2: Select source filesystem
volatile: Select source filesystem
NX7K02-agg# copy tftp: ?
bootflash: Select destination filesystem
debug: Select destination filesystem
log: Select destination filesystem
logflash: Select destination filesystem
nvram: Select destination filesystem
running-config Copy from source to running configuration
slot0: Select destination filesystem
startup-config Copy from source to startup configuration

Nexus 7010 mgmt0 useage opinion
As a Senior Network Engineer I have entered into a bit of a debate with our Architect about the use of the mgmt0 interfaces on the nexus 7010 switch (dual-sups, M2 and F2 linecards).
I would like to know opinion of the Cisco support network.
I believe the mgmt0 interface should left alone for control plane traffic only and Out Of Band management access (ie ssh). At the moment I have made a subnet for all VDCs with the mgmt0 (vrf management) sitting in a common subnet. The physical mgmt0 interfaces from both SUPs are connected a management hand off switch. The mgmt0s also serves as our control plane for VPCs. The VPC peer-link however is using main interfaces of the line-cards.
The opinions;
- The Architect thinks we should use all the mgmt0 interfaces for snmp, ntp, tacacs netflow-analysis and switch management.
- However, I think I should use a traditional Loopback to perform these functions within the linecards. The mgmt0 should only be used if traditional restricted switch access has failed.
My Basis;
the Loopback never goes down, uses multiple paths (the OOB hand off switch could fail closing switch management access completely). The mgmt0 should be used as a last resort of management access to CMP.
Thoughts please - CheersI see your point about wanting to mitigate the impact of losing the OOB switch. I don't think the mgmt0 interface going down is considered the level of failure that will trigger a Supervisor switchover though. That's the way I read the Nexus 7000 HA whitepaper (and what I've seen based on some limited experience with taking apart a 7k pair).
So, no the 7k can't send you an SNMP trap or syslog message if it's configured management path is offline. Mitigation of that could be via your NMS polling the devices's mgmt0 addresses. No response = trouble in paradise. Investigation step would be to log into the 7ks using the loopback IP and local authentication since your TACACS source-interface (mgmt0) is offline and going from there.
The handful I've built (mostly 5k setups) I go for a Cat 3k switch with dual power supplies as the OOB switch. Once one of those is setup and seen not to be DOA, it's generally going to stay up until someone goes in and uplugs it or initiates a system reload. -
Hi,
I needed to add vlans on the bladecenter, So added to ports on the bladecenter and then to the main trunk port of BC as well as i created the vlan on BC.
This BC connects to two main NEXUS 7010 core switch, I added to trunk port of these switches as well and vlan was already created in the nexus core switch.
but i was unable to ping the subnet gateway from the nexus core switch and gets the error as "no route to host"
Is this something there is no routing define for this subnet. As OSPF is running on the core switch.
Thanks
SagarThanks Alex
VLAN was allowed on the trunk, everything related vlan is fine.
but there was no static route defined on the switch as the routing for the subnet was done on the firewall
so what i thought is to give a static route for network with next hop as firewall interface and guess what it started to work
Thanks

Nexus 7010 with F3 line modules. The modules are not "powering on" ?
Hi,
Just tried installing a new Nexus 7010, With a couple of F3 line modules.
I cant seem to figure out how to get them to come online.
They flash with red LED and from a "show module" they show as powered down.
Its a fresh nexus install, What could I be missing here? Do I need to "provision them somehow?
Thanks
LHi,
Its 6. something ( Im not in front of it right now )
And im certain its these ones.
http://www.cisco.com/c/en/us/products/collateral/switches/nexus-7000-series-switches/datasheet-c78-730273.html
They are 48 port , 1/10G fiber. with "8 port groups.."
No idea if this helps at all.
Its a new install,
It contains the default VDC and an admin user. No other config has been done.
