C1000 switch with StackWise

[NUSFETLEN]

Does Cisco C1000 switch support the stacking similar to StackWise? The datasheet states this: "Single IP Management is available on the Cisco Catalyst 1000 Series switches. The uplink ports can be used to connect up to eight switches in a sigle stack and manage them via a single IP address to ease the network management activities like configurations and troubleshooting. This feautre is only available on the Gigabit ethernet models". Does this support MLAG like it is supported by StackWise?

Hi,

The 1000 series does not support StackWise Virtual or traditional stacking like the 9200, 9300, 3800, etc.. You connect the switches together using 1 or 10Gig fiber ports and designate them as stack ports. Once configured, all switches become logically one device with a single IP for management. See link for more info and how to configure the ports.

Hello

 It does not. When it is, they mention on the detasheet like they do here for 9300

"The Catalyst 9300 Series, including the new Catalyst 9300X models, continues to shape the future with continued innovation that helps you reimagine connections, reinforce security and redefine the experience for your hybrid workforce big and small.

The many industry’s first include:

●      Up to 1TB of stacking bandwidth: With Stackwise-1T, Catalyst 9300 switches are the industry’s highest-density stacking bandwidth solution with the most flexible uplink architecture"

I'm adding my reply here in case you need to know how to replace a C1000 stack member switch:

Case: a non master member (sw3) of three C1000 switches stack has become faulty (it is power is dead), and replaced with exact same model through Cisco RMA, so our plan is to have the new one joining the stack with same stack member number and master applies same configuration to it, so, this is how we did it.

Before going through the steps, kindly note that,

• Each switch has 4 TenGigbit Ethernet ports, ports 1 & 2 are used for hstack-ports, 3 & 4 up-links to core-sw.
• SW1 is the master switch with the highest priority,
• hstack ports are:  sw1.TenG2>sw2.TenG1, sw2.TenG2>sw3.TenG1, sw3.TenG2>sw1.TenG2
• stack firmware is 15.2(7)E11.

        Stack Port Status      Neighbors
Switch# Port 1 Port 2        Port 1 Port 2
------- ------ -------      -----------------
1       Ok       Ok           3      2
2       Ok       Ok           1      3
3       Ok       Ok           2      1

Kindly note in my case, when the replacement switch (the new sw3) joined the stack, the other two (sw1 & sw2) suddenly rebooted, it was fine by me as long as configuration remained the same.

For peace of mind, pick a maintenance window before applying these steps with a notification sent to effected users.

Steps:

1. again , pick a maintenance window before applying these steps with a notification sent to effected users. 
2. Connect to master switch (ssh, console) and backup/copy the configuration to your computer.
3. With the new switch is disconnected from the network, power it up and connect to console, the switch will be named "switch" with member order to 1 and priority 1:
   1. Upgrade the new switch to same firmware version of running stack.
   2. Set member number same as old switch: config t, switch 1 renumber 3 {Changing Switch Number 1 to Switch Number 3, New Switch Number will be effective after next reboot}
   3. Set hstack ports: config t, switch 3 hstack-port 1 tenGigabitEthernet 1/0/1, switch 3 hstack-port 2 tenGigabitEthernet 1/0/2 {New Horizontal Stack port will be effective after next reload}
   4. save running-config to startup.
   5. unplug the power cord.
4. Now connect the stack cables, then connect back the power cord.
5. You should have the switch now joining the stack: show switch detail, show switch hstack.

Reminder: Kindly note in my case, when the replacement switch (the new sw3) joined the stack, the other two (sw1 & sw2) suddenly rebooted, it was fine by me as long as configuration remained the same.
