N-Series 6.5 Mixed Stacking Technical Update

N-Series 6.5 Mixed Stacking Technical Update


Background:

With the introduction of the Dell networking operating system 6.5.x.x for N-series campus switching platforms, mixed stacking is supported between:

  • N2000 and N2128PX-ON
  • N3000 and N3132PX-ON
  • N3000 and N3000E-ON

Firmware Revision:

Firmware revisions for mixed stacking are:

  • Advanced Lite (N3000 & N3132PX-ON) or (N3000 & N3000E-ON)
    • L3 routing, stacks to eight units, VLANS: 1024, no MMRP/MVRP
    • Includes BGP
    • N3000N3100AdvLitev6.5.1.x.itb N3000/N3048EP-ON/N3132PX-ON mixed stack
    • N3000AdvLitev6.5.1.x.stk Dauntless L3 only stack (including N3048EP-ON)
  • Standard (N2000 & N2128PX-ON)
    • L2 switching/scale limited routing, stacks to twelve units
    • N2000N2100Stdv6.5.1.x.itb N2000/N2100 mixed stack
    • N2100Stdv6.5.1.x.stk Bristol L2 only stack
    • N2000Stdv6.5.1.x.stk Dauntless N2000 only stack
  • Advanced (N3132PX-ON & N3000E-ON)
    • Full scale routing, stacks to twelve units, VLANs: 4093, MMRP/MVRP
    • Includes BGP
    • N3000N3100Advv6.5.1.x.itb N3000E/N3132PX-ON mixed stack
    • N3100Advv6.5.1.x.stk N3132PX-ON L3 only stack
    • N3000Advv6.5.1.x.stk N3000E only stack

Examples of mixed stacking files for the N3000/N3132PX-ON series:

  • N3100AdvLitev6.5.1.1.stk
  • N3100Advv6.5.1.31.stk
  • N3000AdvLitev6.5.1.1.stk
  • N3000Advv6.5.1.31.stk
  • N3000N3100AdvLitev6.5.1.1.itb
  • N3000N3100Advv6.5.1.31.itb

The .stk files are not new to the Dell networking campus line of products, the new file format .itb is what will be used to support both N3000/N3132PX-ON switches in a mixed stack. This .itb file contains file images for both switches. All future mixed stacking firmware updates will use this file format.

Procedure:

Note: Setting up a mixed stacking environment is a multi-step process with some known limitations for the N3000/N3132PX-ON and N3000/N3000E-ON series switches
- Stack size must be reduced from the maximum of 12 switches to 8
- Only 1024 active VLANs in a configuration range of 1-4093

Mixed stacking update procedure:

  1. Backup your switch configuration.
  2. N3000 series switches will first utilize the N3000AdvLitev6.5.1.x.stk file.
    • Copy and active the .stk file to the N3000 series switches.
      • Update boot code and CPLD if below current revisions and reload the switches.
      • All switches in the stack should now show an active 6.5.1.x image in the "show version" command.
    • Finally copy and activate the N3000N3132PX-ONAdvLitev6.5.1.x.itb image to the N3000 series switches.
  3. N3132PX-ON series switches will follow the same procedure as the N3000 switches.
  4. Once both sets of switches are at 6.5.1.x, power OFF both series switches. Plug in mini-SAS stacking cables. Power ON both series of switches.
  5. Verify connectivity with "show switch" and "show version" commands via the stack master.
Note: Refer to the Upgrading Dell EMC Networking N3000 Series Switches to 6.5.1.x Firmware document included in the N3000 Series, Firmware Version 6.5.1.x zip file available here.
