Network devices-Cisco-Switches (example 3750) stack end configuration Chapter

I came back again, the last two articles introduced the Stack, third firewall IRF. This time to introduce the Cisco stack (stack), although the implementation of the idea is consistent, but the configuration there is a need to pay attention to the place, especially now do the two-tier operators of the network workers, all the producers will be, the pressure is really big.

First, the topological environment:

This project for a national logistics company network bid a part of the scheme, the whole network product word shape, flow parallel structure. The whole program and implementation are planned and implemented by me.

PS: Redundancy, flow parallel

Figure in the network equipment selection:

CISCO-3750 "Dedicated stacking cable"

firewall-asa5515 "Export firewall with failover license"

Firewall-sangfor "Intranet Firewall"

Here are only 3750 stacking configuration methods, the remaining failover ASA is configured with the actual scenario, and an additional article describes. Everyone crossing more attention to this blog, thank you!!

3750 stacking differs from 3550, is true stacking, theCatalyst 3750 series uses stackwise technology, which is an innovative stacking architecture that provides a 32Gbps stacking interconnect that connects up to 9 switches and integrates them into a unified, Logical, converged-optimized devices that allow customers to deploy voice, video, and data applications with greater confidence, 3750 in the form of a backplane stack, where the machine itself has a stacking port for a dedicated stacking line to reach 32G bandwidth, and after the switch is stacked, logically, they belong to the same device. This way, if you want to set up these switches, you can see other switches in the stack as long as you're connected to any one device

(3750 do stacking requires dedicated stacking cable, product comes with 0.5 m stacking cable ).

Let's talk about the prerequisites for configuring the stack:

1. iOS version to be consistent

2. Must use a dedicated cable
   

Example of a fool-type configuration:

1: Physically connect the stacking cable, the connection method for Master's Stack1 is connected to the slave stack2 above. See

2: Open master, do not make any configuration. And so on after the full boot.

3: Open the slave machine.

4: Do not make any configuration. (line plug good, power on automatic stacking election, light Master is the master)

Note: You can also do the stacking configuration first: IP address, priority, etc.

Examples of high-end atmospheric forcing grid operators:

Stack member Master:

Switch 2 Renumber 1 (some users of the device is used, buy back the number of the stack or non-default 1) modification, restart, so that the stack number is OK.

Switch 1 provision ws-c3750g-24ts-1u The Cisco switch has one such command by default

Switch 1 priority 10 (1th device preference changed to 2) priority is higher priority

Save.

Stack member Slave-2:

Switch 1 Renumber 2 (the newly purchased device is factory 1, which is configured as a stack member group i.e. slave, change the number to 2)

Restart

Switch 2 provision ws-c3750g-24ts-1u This bar is configured for stack members

Switch 1 priority 9 (1th device preference changed to 2) priority is higher priority

Save.

Stacking line all screws are screwed and tightened.

In turn:

Stack member Slave-3:

Switch 1 Renumber 3 (the newly purchased device is factory 1, which is configured as a stack member group i.e. slave, change the number to 2)

Restart

Switch 3 provision WS-C3750G-24TS-1U This bar is configured for stack members

Switch 1 priority 8 (1th device preference changed to 2) priority is higher priority

Save.

Stacking line all screws are screwed and tightened.

Note the point:

You can use the Global command Switch 5 renumber 4来 to change the number of devices in a stack (this is to change the number 5th to 4th) The default number is 1, Cisco factory default is 1, but if the device has been stacked before, but the stack number is not cleared, You will need to manually re-execute the above command to change the number.

If you are configuring member group slave in the case of power-up.

Manual execution: #reload slot 2

If you need to delete a stacked configuration:

Direct global configuration mode,

Switch (config) #no switch 2 provision

Switch (config) #do WR ( must be saved after reload)

The following log is the device log for the first time the member group Slave is joined in a standalone operation:

Stacking success, happy.

Perform a stack view command: The show switch stack-ring speed output is as follows.

Questions? : Why is it 16G? Is there a stack interconnect that can reach 32G before?

A: I only use a stack stack line interconnection, because the test environment, is to be surprised to be interesting (: hehe

The following log for my test stack configuration is complete, the member group Slave Unplugged, the single point of failure to simulate the error log.

*mar 1 00:15:14.073:%stackmgr-4-stack_link_change:stack Port 1 Switch 2 have changed to state down

Other:

Check the current stack status:

Show platform Stack-manager All show information for all swap stacks show switch displays summary information for the stack switch

Show Switch 1 shows information for a switch

Show Switch Detail displays information about the stack member details

Show switch Neighbors displays full information about the stacked neighbors

Show Switch Stack-ports displays full port information for the stack switch

Stacking common, at present in some financial, logistics enterprises are very common, and the other side of the enterprise is not bad money, as long as the program is reasonable, the budget cost is not very small, so here again to emphasize the professional quality of the network workers have been seasoned pre-sales program capabilities.

Think of learning as a living habit.
