2960-24TC Ether-Channel

Does anyone know if I can bundle the 4 SFP ports into ether-channel for a 4-gig uplink on a 2960-24TC?

YES, this is possible.
you must have the 2960G-24TC-L model.
this does have the four SFP uplink ports and YES, they can be configured in an etherchannel or trunk configuration.
please see the following link for more info on 2960 etherchannel configuration:

How to configure ether channel

Hi mates,
As far as I know, when you configure ether channel (PAGP/LACP) on two ports, they act like one port. but in reality packets are not sent through both ports. Only one of the ports is used until the actual link fails.
Question is:
I have two switches, each has two SFP ports, I want to connect two switches each other.
how can I make ether channel always use both ports when sending/transmitting packets? I remember it is possible.
thanks for helping :)

HI
i hope this link will help u .
http://www.cisco.com/en/US/products/hw/switches/ps663/products_configuration_example09186a0080094aec.shtml
when u create ether-channel it will automatically load balance based on source/destiantion mac address or source/destiantion ip address.

Ether channel between fiber optic ports any difference?

I will appreciate any help about the below questions.
there are two catalyst 4506 multilayer switches, Two SFP modules are installed on each switches for uplink purpose. (1000 Base SX fiber optic Gigabit ethernet SFP modules)
I want to connect two switches each other. Question is;
1.Can I bundle these two gigabit ports (ether channel) and get Two gigabit connection between switches ?
2.If I can do it, what happens if one of the lines fails?
I know I can configure ether channel between copper fast ethernet ports but I am not sure If I can benefit same feature for 1000 base SX fiber optic ports.
Thank you very much for helping :)

Hi Friend,
You can run a command "sh port capabilities " and that will how that whether that ports are capable of etherchannel or not.
Also AFAIK SFP ports are just the physical medium so it does not make a differece, they should be capable of etherchannel.
Also if one port of the channel goes down traffic will start trasversing through the other port so it will take care as redundancy. It will behave like other etherchannel which you cofnigure with copper ports.
HTH, if yes please rate the post.

What is the maximum number of physical link we can bind to a ether-channel and port-channel

Hi,
I was studying about port-channel & ether-channel and found that, it can be bind up-to 8 ports. So maximum number, we can have of 8 ports or more ?
For binding we should have minimum of 2 ports or 1 ports will work ? For load-balancing purpose, is the port no. would be in a bundle of 2,4 and 8 ?
Thanks

Hi Kathik,
I have gone through one document. It's saying the below mentioned things :
Jun 7, 2012 9:36 PM (in response to Sarabjit)
Re: What is the maximum number of etherchannels we can have?
The maximum number of Etherchannels varies from platform to platform. The maximum number of ports in an etherchannel is either 8 ro 16 depending on the platform. The minimum number of ports in an etherchannel bundle is 1.
Jun 8, 2012 1:27 AM (in response to Sarabjit)
Re: What is the maximum number of etherchannels we can have?
Etherchannels is a Cisco term. Other vendors call them 802.3ad trunks. It's common to see something like this in datasheets:
48 ports 10/100/1000 Mbit/s
802.3ad:
Maximum of 32 groups
Maximum of 8 ports per group

Another document says the below mentioned things for load-balancing :
inally, here is full list of valid load-distribution methods:
•dst-ip—Load distribution on the destination IP address
•dst-mac—Load distribution on the destination MAC address
•dst-port—Load distribution on the destination TCP/UDP port

Ether Channel for WAN connection

We have 2 WAN connection from the ISP 2 links (155M and 300M) . We would like to perform a Etherchannel on this links.
Both the links termination are RJ45 to a Layer 3 switch. Can we configure Ether-Channel ? What is the condition for EtherChannel (eg no signalling from ISP) ?

If you're on an ethernet connection, you should be able to do etherchannel but like what the others have said, you're do not have the same speed for each, load-sharing wouldn't be optimal.
i'd rather do balancing via BGP by choosing what prefix gets advertised to a certain link, so I can at least maximize the two links. I have the same scenario before, I had 1 FastEthernet and 1 STM1 to a service provider, eBGP multihop load-share wouldn't cut it, I have to do manual prefix advertisement.
hope that helps.

STP vs. Ether Channel ; Which one is prefer?

Is Ether Channel an always prefer method comparing to STP? Why? Is there any scenario to use STP better than Ether Channel?

Hi,
Simply put Ether Channel is the technology to combine exisiting Ethernet links and achieving higher bandwidth which is otherwise restricted cause of Layer 2 limitation e.g. can you achieve 4 Gbps bandwidth using GBIC modules/interfaces? The ans is NO. In that case, Etherchannel will bundle all the four inidividual interfaces/GBICs and give you a bandwidth of 4 Gbps.
STP, on the other hand is a technology that will enable you to give a Fault-Tolerant situation when in a Looped environment.
If you require more info please feel free to revert back and I shall be glad to give you more info.
Hope it helps, if it does please rate.

ESW 540 and Ether Channels

We are trying to configure Ether Channels on our ESW 540 switches. We have configured the port(s) and made the physical connections but the Ether channel is only showing up at 1000M. It is my understanding that the port should be displaying at 2000M if configed with one pair of ports. Are there any other settings that need to be completed?
Thank you,
Brock

2960 24TC and 24TT

What are the differences between the ios versions see,sed,fx. I also noticed that the same ios versions are availible for the 2960-24TC,2060-24TT,2960G-24TC?
thx jason

Hi Jason,
The "SEE," "SED," etc., are different branches of the IOS trains available for various platforms, such as the 2960, 3550, 3560, 3750, etc.
12.2(25)SE is the IOS train for 12.2 that is designated for the above mentioned switch platforms. Due to new features and/or hardware support, new branches are created, while others are closed.
The current latest IOS in the 12.(25)SE train is 12.2(25)SEE. Other branches such as the 12.2(25)SED, SEC, SEB, and SEA have been closed.
There's a good whitepaper that goes into greater detail of how this all works:

Can we create ether-channel

HI
Can we create ether channel in this scenario.
for eg Switch1 in the ground floor and two switches on the first floor the two switches on the first floor are cascaded and from the ground floor switch two links are going to the two switches.
Thanks
Mahmood

Hi Mahmood,
You can create an EtherChannel on a standalone switch, on a single switch in the stack, or on multiple switches in the stack (known as cross-stack EtherChannel).
See Figure 33-2 and Figure 33-3 in the below mentioned link

2960 Stack Port Channel Question

I have a 2960 stack with 2 WS-C2960S-48FPD-L distribution switches running c2960s-universalk9-mz.150-2.SE2.bin.
I then have three stand alone 2960S-48 access switches running the same code.
I will have two ten Gig uplinks in a port-channel back to a 6500. I have this config. however
I would like to have port-channel between each of the distribution switches in the stack and each of the stand alone access switches.
So as an example:
distribution switches: port 1/0/48 and 2/0/48 in port channel 1
access switches: 1/0/51 and 1/0/52 in channel-group 1 active
Am I right in thinking that because these port channels come off of two different switches in a 2960 stack that they need to be LACP and the ports on the access switches need to be in "channel-group X active". And does it need to be in active mode on both sides?
Thank You in advance

Yes, both sides must have identical channel mode.

Make sense. Look at the speed of both ports. They are not the same. And this is why Gi1/0/1 is suspended.
Gi 1/0/1 could potentially have a faulty cable. You could try running a TDR to determine.
1. Command: test cable tdr interface Gi 1/0/1;
2. Wait for approximately 5 to 7 seconds;
3. Command: sh cable tdr interface Gi 1/0/1;
4. Post the output to #3.

I wanted to know whether i need to upgrade the LMS? if so then will the license on my existing LMS work on the new/Upgraded LMS
BR// Rajiv

Hello,
When searching a documentation for LMS device support, it is better to search if exact SNMP sysObjectID is supported. You can execute following command on the LMS server to get the switch sysObjectID (find snmpwalk.exe file on your server, this is an example for default location):
C:\Program Files\CSCOpx\objects\jt\bin>snmpwalk.exe -v2c -c 1.3.6.1.2.1.1.2
(1.3.6.1.2.1.1.2 is the OID for sysObjectID variable.)
I'm not sure if there is a device package for the particular switches, but you can always try to search for updates via LMS Web GUI:
Common Services
> Software Center > Device Update
and:
Common Services > Software Center > Software Update
If your LMS server has Internet access, and you have valid CCO user ID with privileges to download the software, you can download and install all minor updates and device packages... Everything offered for download when using previous Web GUI tools is free if you have paid Cisco SAS support and works with the same LMS license you already have.
Do not forget to check for prerequisits (for example, sometimes is needed to install Mdf update for Common Services before installing some RME update...)
Best regrads,
Jasmina

Ether Channel (port aggregation)

No matter LACP or PAgP is used, is it possible to do port aggregation on a Server with NIC 1 & NIC2 respectively connecting to different Switches which are then having the same uplink to higher level?
as follows : -
Server NIC # 1 ------ Switch #A ----\
---- LAN
NIC # 2 -------Switch # B ---/
My understanding is that it cannot, can it ?
Rgds,
Raymond.

THanks, that's what i'd been understanding, yet, someone else post me this answer, Quote,
For your case, the LAN switches won't care how you send out the packet, it just treat the two NICs as two NICs, your server need to deal with the packet/session aggregation. It works because we suppose your server don't have any STP issues.
Kind Regards,
Bong So
Professional Services, Equant HK
UNQuote
I shall test ... the actual case is happening with our being installed IBM BladeCenter Server, having the NIC1 and NIC2 internally wired to CIGESM switch 1 and 2; and the NIC's are Broadcom capable of using Virtual adapters in either modes, one which is LACP.
Thanks again.
Raymond.

How do I set up ether-channel between 4507s

This should be simple, but it's not.
I have three 4507s; one is an edge, and the other two are core switch/routers. I want two cables going from the edge ( on separate blades) to trunk to each of the core 4507s. This would mean four wires leaving the edge, and two wires into each core. thanks

Hi
you don't say what version of IOS you are running but attached is a link to config for 4500 etherchannel. This will apply to all IOS versions.
