Hi All , n7k1 ---VPC --- n7k2 ..both have 6.2(2a) image ..if I reload n7k1 with the new image is 6.2(20) and once n7k1 comes online, will three be any breakage of VPN peer-link due to mismatch of OS versions of n7k1 and n7k2? After 20 minutes ,reload of n7k2 with 6.2(20) will be done once n7k1 is working fine with new code 6.2(20) ..what could be the status of vpc and peer keepalive in the above scenario and how would be the traffic flow from down stream switches which are connected to both n7ks using fabric path.. scenario : n7k1 (6.2(20)) - vpc - n7k2 (6.2(2a)) ..

Hi Mark, We are planning to proceed with traditional way ie cold restart (NON-ISSU) procedure for OS upgrade. The last point I would like to check with you is, After changing the boot version to the new code and before rebooting nexus 7010 switches ( which has dual SUP2E modules), is it mandatory to remove standby SUP 2E module so that switch boots with newer code and then insert back the standby SUP2E as soon as switch comes online, which syncs with Active SUP2E? Many Thanks...

Hi Mark , Information provided by you is very helpful. Is there any way to check whether existing modules on my nexus 7010 supports new image which I am going to load ? I have one more question related to EPLD upgrade .In the cisco documentation it was mentioned that EPLD image updates are not mandatory unless otherwise specified. The EPLD image upgrades are independent from the Cisco NX-OS In Service Software Upgrade (ISSU) process, which upgrades the system and kickstart images with no impact on the network environment. How to determine whether a new image needs a EPLD upgrade .EPLD upgrade is only for I/O modules, so in case EPLD is not upgraded then will it power down existing modules. We have EPLD image on the nexus 7010 but it's not installed. Any command which shows EPLD versions of the existing modules. If we go with hard reboot ie NON-ISSU procedure to load the image into nexus 7010, can we load target image directly onto nexus 7010, instead of loading intermediate images and reloading the box with an intermediate image before reloading the box with a target image Many Thanks in advance.

Hi Mark , Thank you very much for the reply and information . We are going to take downtime as we are planning for hard reboot of switches after each code upgrade. Could you please provide us step by step procedure to upgrade nexus 7010 ( hard reboot ie traditional way of upgrade) , which has dual sup 2E module in it. you have mentioned that " When you perform an ISSU to Cisco NX-OS Release 6.2(8)/6.2(8a)/6.2(8b) from an earlier release, the service “pixm_vl” in the switch might crash. Make sure that you review all the Upgrade/Downgrade issues in the “Resolved Caveats” section of the respective releases. " Since we are not going with ISSU procedure to upgrade nexus 7010 switches, does the above-mentioned bug still hit when we hard reboot the switch with 6.2(8a) OS ?

Hi Experts , We are planning for OS upgrade on Nexus 7010 switches ( each has dual SUP 2E) from 6.2.2 to 6.2.20 . As per Cisco documention , we have to go for intermediate release ie 6.2.8a before going for 6.2.20. When we searched few blog related to OS upgrade using ISSU , most of the guys were preferring cold restart procedure instead of ISSU. in Few cases , ISSU installation got stopped at the middle. Example is as below. The ISSU installed correctly, although during the failover to the standby supervisor the OSPF process stalled and never recovered. I had to reload the entire chassis and roll back to original code. So for me....ISSU just needs an E, and we have the word ISSUE. Need valuable suggestion from experts on the below points . 1. ISSU (or) Cold restart , which method is most successful one In the below cisco documentation , it was mentioned that " Ensure your hardware is supported, this is very important. ie investigate EPLD updates, which are updates to actual hardware line cards but they were not needed. Please see the following link for EPLD assistance - https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/best_practices/cli_mgmt_guide/cli_mgmt_bp/epld_upgrade.html 2.Does nexus 7010 switches requires EPLD upgrade too ? When we executed few commnds related to EPLD on nexus 7010 switches we are getting error messages and when we serached in google we could see below one. Symptom : The show install epld status command returns “Could not pull epld logs from plog.” Conditions : This problem sometimes occurs under these conditions: Upgrade the active supervisor PMFPGA. After the supervisor resets itself and boots up, enter the show install epld status command. Workaround : This issue is resolved. CSCuh57710 Suggetions would be appreciated as we are performing OS upgrade on nexus 7010 first time.

Hi Balaji , Thank you for the information. as per the link shared by you we could see below info. o configure the source channels for a SPAN session, perform this task: Command Purpose switch(config-monitor)# source { interface {port-channel | san-port-channel } channel-number rx | vlan vlan-range | vsan vsan-range} Configures port channel, SAN port channel, VLAN, or VSAN sources. The monitored direction can only be ingress and applies to all physical ports in the group. For VLAN or VSAN sources, the monitored direction is implicit. The following example shows configuring a port channel SPAN source: switch#configure terminal switch(config)# monitor session 2 switch(config-monitor)# source interface port-channel 1 rx But as per version 6.x guide we could see below info. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus5500/sw/system_management/6x/b_5500_System_Mgmt_Config_6x/b_5500_System_Mgmt_Config_602N12_chapter_010000.html Configuring Source Port Channels , VSANs, or VLANs You can configure the source channels for a SPAN session. These ports can be port channels SAN port channels, VSANs and VLANs. The monitored direction can be ingress, egress, or both and applies to all physical ports in the group. Procedure Command or Action Purpose Step 1 switch# configure terminal Enters global configuration mode. Step 2 switch(config) # monitor session session-number Enters monitor configuration mode for the specified SPAN session. Step 3 switch(config-monitor) # source { interface { port-channel | san-port-channel } channel-number [ rx | tx | both ] | vlan vlan-range | vsan vsan-range } Configures port channel, SAN port channel, VLAN, or VSAN sources. For VLAN or VSAN sources, the monitored direction is implicit. Example The following example shows how to configure a port channel SPAN source: switch# configure terminal switch(config)# monitor session 2 switch(config-monitor)# source interface port-channel 1 rx switch(config-monitor)# source interface port-channel 3 tx switch(config-monitor)# source interface port-channel 5 both ------> Both tx and rx monitoring is done switch(config-monitor)# Looks like OS 6.2 supports SPAN of port-channel is both directions , Can someby please confirm it ?

Hi Experts , I have a small doubt regarding the span of ethernet ports , which are part of port-channel on nexus 5596 switch. As per Cisco documentation , we can SPAN port-channel and only RX traffic can be monitored. I have 2 port-channels on Nexus 5596 ( VPC+ is configured between nexus 5596-1 and nexus 5596-2 ) as below. Port-channel 10 - eth 1/1 , eth 1/2 and eth 1/3 (Trunk ports allowed multiple vlans) Port-channel 11 - Eth 2/1 , eth 2/2 and eth 2/3 (Trunk ports allowed multiple vlans). I have below questions. 1. Can we configure SPAN for individual ethernet ports, since they are part of port-channels? 2. If yes, can we enable monitor both TX and RX traffic? If we monitor multiple VLANs (span multiple VLANs), was there any limitations like how many VLANs can be monitored? Monitoring is only for RX traffic in case of multiple VLANs monitoring using SPAN. Please provide me few configuration examples as we got the requirement to configure SPAN for multiple VLANs and individual ethernet ports, which are part of port-channels as above.

Hi , T If the other end device and the switch (depending on your platform and IOS version) supports 802.3ad, you can use channel-group mode mode active, which is the IEEE equivalent of mode 'desirable.' If one or both of the devices do not support 802.3ad, then you can use channel group mode on, on the switch, which will disable negotiation of the channel and forces the LAN ports to channel unconditionally. With rgds, Satish
