Nexus 5k Scheduled Reload

Hi,
Is there a command similar to "reload in" for Nexus 5k and 3k.
I have been searching, but couldnt find, hence thought of asking the expert community here.
Thanks

Hi Kishore,
The Reload in option was removed in NX-OS as we have checkpoint option. Mostly we use reload in option, if we need to back out any configurations and reset the box to original state. If this is what you are trying, you can achieve this with the checkpoint and rollback options.
Below link for your reference,

Thanks,

Nexus 5548 scheduled reload

I'm working with a 5548 remotely and need to make some routing changes. When working with remote switches and routers in the past, I've always included a reload with a delay just incase I lock myself out with the commands that I will be issuing. I see a reload command in NX-OS but don't see a way of setting up a delayed reload. Does anyone have any ideas on how I can do this?

Unfortunately the 5500 series does not have this command.

ME 3400 - Scheduled reload does not occur

Hi there,
we try to schedule a reload during off-pick hours on several ME3400 equipped with "me340x-metroipaccess-mz.122-37.SE1" IOS. Altough the "reload at 03:00" and any other form of this command (such as reload in 333 or reload at 03:00 24 Dec) is well accepted, the "sh reload" says "No reload is scheduled.".
Any suggestions?
Thank you in advance.

You must set your pref credentials for 2 targets to run this process.
first, set the pref credentials for the host that the db resides on
then set the pref credentials for the db itself. You must set both the normal username for the db and the host user.
Yes, you must set the host pref credentials in both places.
Hope this helps,
Landon

Nexus 3548 reload after Jumbo Frames

I have a Nexus 3548... I know the Catalyst switches require a reload after enabling jumbo frames but does a Nexus require a reload?
Also, is there a way to verify other then doing a int counter detail command?
Thanks in advance.

As for the verify, If I run "sh queuing int eth1/6" as per instructions I get Ambiguous command pointing to the "n" in "int"

Reload command

Hello,
Is it possible to have a router schedule itself to reload every night or once a week?
We have some Cisco 3g wireless routers in remote locations and if we lose connectivity we have to get someone to power cycle the router to get the 3g working again.
I have added an SLA script to the router that pings Google and if it can't it will do a test on the cellular modem which will power cycle that part of the router only which may help.
With a local schedule reload on top of the SLA I'm sure it will be much more reliable. I have a schedule tool that can do remote reloads but if the router is down then we are stuck and home the SLA works.
Thanks

L2TP script to initiate a router reload when tunnel goes down - working

Hi,
Just thought I would post a working EEM script on doing a router reload when the L2TP tunnel goes down....
I am using a 3825 router to initiate a site-to-site tunnel with a 3rd party vpn service - StrongVPN. On the odd occasion when the tunnel goes down, the l2tp tunnel state goes to "no session left" and the virtual-ppp1 interface - which is tied to the l2tp vpn - goes down. Unfortunately, because I have no control on the far end router, the only way to bring it back up is thru a router reload....
Here you go:
event manager applet L2TP-DOWN
event syslog pattern "%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-PPP1, changed state to down"
action 1.0 syslog msg "The L2TP VPN is down"
action 1.1 cli command "enable"
action 1.2 cli command "reload in 10" pattern "confirm"
action 1.3 cli command ""
action 1.4 syslog msg "EEM scheduled reload in 10 minutes"
event manager applet L2TP-UP
event syslog pattern "%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-PPP1, changed state to up"
action 1.0 syslog msg "The L2TP VPN is up"
action 1.1 cli command "enable"
action 1.2 cli command "reload cancel"
Jason

Hi Arie,
So, here is the script I am using....
When the L2TP tunnel goes to "no sessions left", the virtual-ppp1 interface goes down. That's the typical message I get when it goes down. So, when I reboot the router, the script shows the message that the virtual-ppp1 interface is up when the L2TP tunnel comes up. I checked the debugs and that is the behaviour when the tunnel goes up / down...
Here you go:
event manager applet L2TP-DOWN
event syslog pattern "%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-PPP1, changed state to down"
action 1.0 syslog msg "The L2TP VPN is down"
action 1.1 cli command "enable"
action 1.2 cli command "reload in 10" pattern "confirm"
action 1.3 cli command ""
action 1.4 syslog msg "EEM scheduled reload in 10 minutes"
event manager applet L2TP-UP
event syslog pattern "%LINEPROTO-5-UPDOWN: Line protocol on Interface Virtual-PPP1, changed state to up"
action 1.0 syslog msg "The L2TP VPN is up"
action 1.1 cli command "enable"
action 1.2 cli command "reload cancel"
Thanks.

Blank ACL required?

Hi,
I have had a guest VLAN running for a few weeks and today after a scheduled reload of our systems we had a wireless problem.
Our configuration has clients authentication on the WLC web portal, and then have access to Internet only. This access is controlled with an ACL on the core switch.
The only change to the system that we know of is that the WLC was reloaded over the weekend, and then this morning users are unable to access the net, although they get an IP from DHCP.
After some troubleshooting I suspected an ACL, so I took out the ACL on the core switch, to no effect. So I looked at the WLC, and I found an unused ACL that I created a few weeks ago - I verified that both our WLANs have no ACL configued (in pre-auth and in override ACL) but I wasn't able to remove the ACL totally as the system says "Error! ACL is in use".
So I created an ACL on the WCL for open access, and applied it to the guest WLAN and users were then able to have access.
I suspect that somehow the WLC was applying this old ACL, even though the interface did not display this. This is going to be a bit of a tricky one to reproduce, but I'll try when I get some time and then I will report it to TAC.
Paul

I believe this will only delete an individual rule in the ACL.
Even in the CLI I get the error message "Error! ACL is in use" which confirms the systems behavior, that the ACL is in fact in use.
It seems pretty clear, I have to take the ACL out of use before I can remove it - but unfortunately the web management tools report that there is no ACL configured for any interface.
The CLI disagrees:
interface acl WLAN Student_Internet_Access_Only
What I suspect is required, is a way to remove the above line - but there seems to be no syntax to do this.
(QCA-WLC1) >config interface ?

Nexus 7000 - unexpected shutdown of vPC-Ports during reload of the primary vPC Switch

Dear Community,
We experienced an unusual behavior of two Nexus 7000 switches within a vPC domain.
According to the attached sketch, we have four N7Ks in two data centers - two Nexus 7Ks are in a vPC domain for each data center.
Both data centers are connected via a Multilayer-vPC.
We had to reload one of these switches and I expected the other N7K in this vPC domain to continue forwarding over its vPC-Member-ports.
Actually, all vPC ports have been disabled on the secondary switch until the reload of the first N7K (vPC-Role: primary) finished.
Logging on Switch B:
20:11:51 <Switch B> %VPC-2-VPC_SUSP_ALL_VPC: Peer-link going down, suspending all vPCs on secondary
20:12:01 <Switch B> %VPC-2-PEER_KEEP_ALIVE_RECV_FAIL: In domain 1, VPC peer keep-alive receive has failed
In case of a Peer-link failure, I would expect this behavior if the other switch is still reachable via the Peer-Keepalive-Link (via the Mgmt-Port), but since we reloaded the whole switch, the vPCs should continue forwarding.
Could this be a bug or are there any timers to be tuned?
All N7K switches are running on NX-OS 6.2(8)
Switch A:
vpc domain 1
peer-switch
role priority 2048
system-priority 1024
peer-keepalive destination <Mgmt-IP-Switch-B>
delay restore 360
peer-gateway
auto-recovery reload-delay 360
ip arp synchronize
interface port-channel1
switchport mode trunk
switchport trunk allowed vlan <x-y>
spanning-tree port type network
vpc peer-link
Switch B:
vpc domain 1
peer-switch
role priority 1024
system-priority 1024
peer-keepalive destination <Mgmt-IP-Switch-A>
delay restore 360
peer-gateway
auto-recovery reload-delay 360
ip arp synchronize
interface port-channel1
switchport mode trunk
switchport trunk allowed vlan <x-y>
spanning-tree port type network
vpc peer-link
Best regards

Problem solved:
During the reload of the Nexus 7K, the linecards were powerd off a short time earlier than the Mgmt-Interface. As a result of this behavior, the secondary Nexus 7K received at least one vPC-Peer-Keepalive Message while its peer-link was already powerd off. To avoid a split brain scenario, the VPC-member-ports have been shut down.
Now we are using dedicated interfaces on the linecards for the VPC-Peer-Keepalive-Link and a reload of one N7K won't result in a total network outage any more.

Nexus - How to schedule a rollback

I have a Nexus 7000 that I'm trying to test a scheduled rollback on, but I cannot seem to find any command syntax that support this. I have NX-OS version 6.2x.
The checkpoint and rollback commands are nice, but no way to schedule a rollback.
Please help! Looking for any type of solution.
Thanks in advance,
Andy

Thanks Bilal. That solution seems to make sense; however, the job status shows a code of Failed (75). I cannot get any job to execute. I thought it was maybe my credentials but the aaa authentication statement I use works fine. I enabled the log file size in the scheduler to 1024, but there is no output when I issue a "show scheduler logfile".
I'm at a loss right now as to why it's not kicking any job off.

WiSM controllers reload scheduler???

WCS 4.2.62.11
WiSM controllers 4.1.185
Is there any way to schedule a WiSM controller's upgrade? We would like to upgrade our WiSM controllers from 4.1.185.0 to 4.2.99.0 through some kind of scheduler. We could download the new image to the WiSM blades the day before, but we would like to schedule a controller reload for some time around 5 in the morning. We are aware that the APs will download a new image and it would take a bit for them to be operational, but we have enough time before production hours.
Through Ciscoworks we could schedule a module reset which will bring the new image to active (we would set the primary image load value ahead of time), but we would like something a bit more gracious. I haven't been able to find anything under ciscoworks or WCS where one could schedule a controller reload.
Perhaps there is a CLI command on WCS that I could cron.
Any ideas are appreciated.
Thanks.
Jorge Jiles

We have used expect scripting in the pass, but for security reason we stopped. In any case, in the script what would the command be to reload a wireless controller from a WiSM blade??? I could reload the blade, but I can do this from Ciscoworks as well.
Thanks.
Jorge.

Nexus 5596 reloads with redundant PS after 1 PS breaks down

Hi All,
We have a Nexus N5K-C5596UP with redundant power supply. 2 x N55-PAC-1100W.
Last week 1 of those PS broke down. When this happened the chassis reloaded. I wouldn't expect this to happen.
Does anyone have an idea of why this happened?
Our NX-OS version is n5000-uk9.5.2.1.N1.1a.
Thanks,
Joris

Joris, good day.
I suppose it's your case: http://www.cisco.com/c/en/us/support/docs/field-notices/638/fn63893.html

10G SFP Module absent after reload in Nexus 5548UP

Hi there,
i have a problem concerning two new 5548UP.
After a reload, the 2x2 10G SFP Modules SFP-10G-SR are displayed as "sfpabsent" on a random basis.
When i plug it out and afterwards in again, they work fine an the VPC-Peer link across the two switches comes up.
My 1G SFP modules are all working correctly.
I tested firware version 6.0 and 5.2.
Any suggestions?
Thank you very much!

Hi,
We had the same problem with a Nexus 5596 in 5.1(3)N2(1a) last night:
%NOHMS-2-NOHMS_ENV_ERR_FAN_SPEED: System minor alarm in fan tray 1: fan speed is out of range on fan 2. 5812 to 12500 rpm expected. 4072 rpm read
%NOHMS-2-NOHMS_ENV_ERR_FAN_DOWN: System minor alarm on fans: One fan missing or failed
%NOHMS-2-NOHMS_ENV_ERR_FAN_RECOVERED: Recovered: System minor alarm in fan tray 1
%NOHMS-2-NOHMS_ENV_ERR_ALL_FAN_UP: Recovered: System minor alarm on fans: One fan missing or failed
%PFMA-0-SYS_SHUTDOWN_FAN_DIR_MISMATCH: System shutdown in 60 seconds due to fan dir mismatch
%NOHMS-2-NOHMS_ENV_ERR_FAN_DIR: System major alarm: fan direction mismatch with other fan(s)
%PFMA-0-SYS_SHUTDOWN_FAN_DIR_MISMATCH: System shutdown in 55 seconds due to fan dir mismatch
%PFMA-0-SYS_SHUTDOWN_FAN_DIR_MISMATCH: System shutdown in 50 seconds due to fan dir mismatch
After reseating the FANs the switch came up. We'll open a TAC case.

Nexus 5000 vPC suspended during reload delay period

Hi ,
after reloading on vPC-Peer-Switch be box comes up and all vPC-Member-Ports on the box are in suspended state until the reload delay time expired.
Unfortunately the link of the vPC-Member Ports are already up. This behaviour leads us in some problems if we connect a Cisco-UCS-FI with a LACP-Portchannel to a vPC on N5K.
Because the link of the suspended Port is up the FI detects the port also as up and running and set it to individual state, because of missing LACP-BPDUs, So at this time the FI hast two uplinks, one Port-Channel and one individual Ports. After 30 seconds the FI starts to repinning the servers over these two uplinks. Because the individual Port is not in forwarding state an the reloaded N5K until reload delay timer expired.
So during this period all the servers which are pinned to the individual Port are blackholed.
Possible Workarrounds
1. Creating a Pin-Group for the Port-Channel and pinning all Servers to this Pin-Group to avoid in case on channel-Member goes to individual state, any server is pinned to this individual Port . This could be a solution
2.Configuring the Port-Channel on FI for "suspend individual". Unfortunately I could not find a way to achive this. This would avoid that the individual Port is considered as possible uplink-port, so no pinning to the individual Port would happen.
3. Find a way that during the delay restore time on the suspended vPC-Member-Ports also the link is down. (In my opinion this would be the best way)
I am not sure if configuration of "individual suspend" on the vPC on the N5K would help.
any other ideas?
Hubert

What I really want is a command I can use to prevent VPC from turning off ports at all. I'd much rather have an active-active situation than have my entire network go down just because the primary VPC peer rebooted. VPC is not designed correctly to deal with that situation. And yes, it has happened. Multiple times with different VPC keepalive setups.

Nexus 5000 vpc and fabricpath considerations

Hello community,
I'm currently in the process of implementing a fabricpath environment which includes Nexus 5548UP as well Nexus 7009
NX OS on N5K is 6.0(2)N1(2)
Regarding the FP config on the N5K I wonder what is the best practice for the peer-link. Is it necessary to configure the Portchannel like below:
interface port-channel2
description VPC+ Peer Link
switchport mode fabricpath
spanning-tree port type network
vpc peer-link
There are several VLANs configured as FP.
As I understand we can remove the command:
spanning-tree port type network
Can anyone confirm this ?
Also I noticed a "cosmetic" problem. On two port 1/9 and 1/10 on both N5K it isn't possible to execute the command "speed"?!
When the command speed is executed I receive the following error:
ERROR: Ethernet1/9: Configuration does not match the port capability
Also please notice after the vPC and FP configuration we don't do a reload!
Thanks
Udo

Hi Simon -
Have done some testings in the lab on ISSU with FEXes either in Active/Active and Straight-through fashion, and it works.
Disabling BA on N5K(except the vPC peer link) is one of the requirements for ISSU .
In a lately lab testing with the following topo, BA is configured on the vpc 101 between the N5Ks and Cat6k. We have a repeated regular ping between the SVI interfaces of c3750 and Cat6K.
                      c3750
                         ||
                      vPC
                         ||
    N5K =====vPC====== N5K
                          ||
                     vpc 101
                          ||
                     Cat6k
When we changed the network type to disable BA, we observed some ping drops, which around 20-30.
I am not sure what your network looks like, hopefully this will give you some ideas about the ISSU. As a general recommendation, schedule a change window for some changes or even ISSU.
regards,
Michael
