Nexus 5548UP non-disruptive upgrade.<\/strong><\/span><\/h1>\n

In the past we have done upgrades, but most of the time cisco mentioned non-disruptive, but most case 6.0X or old have disruptive upgrade in my experience.<\/p>\n

Finally i got a chance to write upgrade procedure for others to refer ;<\/p>\n

NXOS 7.X onwards cisco have made lot of improvements\u00a0 that makes for the engineers have easy task than night mare.<\/p>\n

Below Steps exactly i followed and it was smooth upgrade and no service interruption other than Orphan ports connected device will go down as this is expected and limitation- dual homed devices have no service interruption since data plane not broken while upgrading time.<\/p>\n

Upgrade Guidelines<\/strong><\/span><\/h2>\n

When upgrading system software, follow these guidelines:<\/p>\n

Configuration changes –\u00a0 You cannot enter global configuration mode during an upgrade. You should save, commit, or discard any active configuration sessions before you upgrade or downgrade the Cisco NX-OS software image. The active configuration session is deleted without a warning during a reload.<\/p>\n

Use the show configuration session summary command to verify that there are no active configuration sessions.<\/p>\n

switch#\u00a0show configuration session summary<\/b><\/div>\n
There are no active configuration sessions<\/div>\n

 <\/p>\n

Further more you can refer cisco site document ;<\/p>\n

https:\/\/www.cisco.com\/c\/en\/us\/td\/docs\/switches\/datacenter\/nexus5500\/sw\/upgrade\/714_N1_1\/n5500_upgrade_downgrade_714_n1_1.html<\/p>\n

 <\/p>\n

Quick checks – make sure your upgrade path is correct :<\/p>\n

\"\"<\/p>\n

If you have lower version of NXOS 5.0 or 6.0, you need to follow the upgrade path\u00a0 step by step upgrade to final version.<\/p>\n

Even though\u00a0 i have tested and working as non-disruptive upgrade, since we are upgrading this on Live environment, so i suggest to have change maintenance windows, if any unforeseen occurs.<\/p>\n

Requirement :<\/p>\n

download the kickstart and system image<\/p>\n

console cable<\/p>\n

physical access to kit<\/p>\n

make sure user have admin right<\/p>\n

take backup of running config.<\/p>\n

Here simple topology to understand :<\/p>\n
