Setup Port Channel on Cisco 3560

I have 2 Layer3 switches. (Cisco WS-C3560X-24P-L). I am setting:

interface FastEthernet0/1

 channel-group 1 mode on

!

interface FastEthernet0/2

 channel-group 1 mode on

!

interface FastEthernet0/3

 channel-group 1 mode on

!

interface FastEthernet0/4

 channel-group 1 mode on

!

interface Port-channel 1

 no switchport

 ip address 192.168.1.2 255.255.255.0

Other switch is same but using 192.168.1.1 255.255.255.0

I am getting connectivity. But Basically would like to have fail-over and load balancing.

So out of the 4 fast Ethernet ports. If one fails. There should still be connectivity.

Get rid of your IP addresses.  Port bonding is a layer 2 game and you don't need them.

Here is an example of a working LACP etherchannel configuration on a WS-C3560G-24TS running IPservices 12.2(50)SE4.  The config on the partner switch is identical.

Cisco 3560 Switches Installing SFP Modules

Removing and installing an SFP module WS-C3560V2-48TS-S can shorten its useful life. Do not remove and insert SFP

modules more often than is absolutely necessary.

Step 1 Attach an ESD-preventive wrist strap to your wrist and to a bare metal surface on the chassis.

Step 2 Find the send (TX) and receive (RX) markings that identify the top side of the SFP module.

Note On some SFP modules, the send and receive (TX and RX) markings might be replaced by arrows

that show the direction of the connection, either send or receive (TX or RX).

Step 3 Align the SFP module in front of the slot opening.

Step 4 Insert the SFP module into the slot until you feel the connector on the module snap into place in the rear

of the slot.

Step 5 For fiber-optic SFP modules, remove the dust plugs from the optical ports, and store them for later use.

Caution Do not remove the dust plugs from the fiber-optic SFP module port or the rubber caps from the

fiber-optic cable until you are ready to connect the cable. The plugs and caps protect the SFP module

ports and cables from contamination and ambient light.

Step 6 Insert the cable connector into the SFP module:

 • For fiber-optic SFP modules, insert the LC or MT-RJ cable connector into the SFP module.

 • For copper SFP modules, insert the RJ-45 cable connector into the SFP module.

Note When connecting to 1000BASE-T SFP modules, be sure to use a twisted four-pair, Category 5 cable.

3560 Showing Garbage in Console

Cisco WS-C3560X-48PF-S  series products have two main categories, Cisco 3560V2 and Cisco 3560X, 3560V2 is FE based switch while 3560X is GE based switch, the previous Cisco 3560, 3560G and 3560E are end of sales now and replaced by Cisco 3560V2 and Cisco 3560X. Cisco Catalyst 3560 v2 Series consumes less power than its predecessors. The 3560-X Series Switches is an enterprise-class lines of stackable and standalone switches.

I have few 8-port 3560's (WS-C3560-8PC) that I have been using to roll out a Metro Ethernet upgrade.  I have one switch that originally configured just fine, but now it is displaying all kinds of gibberish in the console window.  I can telnet into the switch ok.  The configuration register on it is set to 0xF.  But I have tried using a serial connection from multiple computers, and they all show the same garbage.  I have 4 of these switches next to each other.  They all have the same IOS: 15.0(2)SE image.  They all have the same configuration register.  I can console into all of them except for this one switch.

I have verified my terminal settings, and they are as suggested:

Speed: 9600 bps     

Databits: 8      

Parity bits: 0     

Stop bit: 1     

No flow control

This time, I have tried changing to all of the following baud rates, and they all produce gibberish:

1200 bps     

2400 bps     

4800 bps     

9600 bps     

19200 bps  

38400 bps     

57600 bps     

115200 bps

configure terminal

Enter global configuration mode.

radius-server key string

Specify the shared secret text string used between the switch and all RADIUS servers.

Note       The key is a text string that must match the encryption key used on the RADIUS server. Leading spaces are ignored, but spaces within and at the end of the key are used. If you use spaces in your key, do not enclose the key in quotation marks unless the quotation marks are part of the key.

radius-server retransmit retries

Specify the number of times the switch sends each RADIUS request to the server before giving up. The default is 3; the range 1 to 1000.

radius-server timeout seconds

Specify the number of seconds a switch waits for a reply to a RADIUS request before resending the request. The default is 5 seconds; the range is 1 to 1000.

radius-server deadtime minutes

Specify the number of minutes a RADIUS server, which is not responding to authentication requests, to be skipped, thus avoiding the wait for the request to timeout before trying the next configured server. The default is 0; the range is 1 to 1440 minutes.
