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

VLAN Tagging ESW-540 and 3750g

Hi everyone!
I'm a self taught cisco type person who really specialises in ASA rather than routers, but have fumbled my way through many a task with the help of this site and google... However! I am currently tasked with setting up a network, pretty much from scratch, that requires some fairly hefty VLAN deployment.
My hardware on hand (already existed so can't can't change anything easily) 5x ESW-540-48 Switches, 1x3750g switch, 1x2811 router.
I don't believe the router should be required as the 3750 is capable of intervlan routing. So what i'm trying to achieve is as follows:
VLAN 1 - 172.16.8.0/22 (A)
VLAN 2 - 10.0.2.0/24     (B)
VLAN 3 - 10.0.3.0/24     (C)
VLAN 4 - 10.0.4.0/24     (D)
VLAN 5 - 10.0.5.0/24     (E)
VLAN 6 - 10.0.6.0/24     (F)
VLAN 7 - 10.0.7.0/24     (G)
VLAN 8 - 10.0.8.0/24     (H)
VLAN 9 - 10.0.9.0/24     (I)
Server Room - Servers connected to the 3750G
3750G connected to 5 ESW switches distributed around the building.
ESW-1 Will have VLAN(A) and VLAN(B) devices connected, specified at port level.
ESW-2 Will have VLAN(A) and (C) devices connected, specified at port level.
ESW-3 Will have VLAN(A), (D), (E) and (F) devices connected, specified at port level.
ESW-4 Will have VLAN(A), (G) devices connected specified at port level.
ESW-5 Will have VLAN(A), (H) and (I) devices connected, specified at port level.
Now at one point I actually had the VLAN's *working* in that I could specify an IP address and could ping to and from it! However DHCP wasn't passing despite numerous attempts with DHCP relay and IP-Helper configurations.
Also I was having issues with VLAN 1 as the native VLAN, the ESW switches don't allow you to do much with them, as they 'weren't created by the user'. So tried switching that out to VLAN11 also but with very little success there (I had to change the native vlan on all trunks to VLAN 11)
All the 10.x.x.x addresses need to be able to communicate with each other
All the ESW switches need to be able to handle their respective VLAN's as well as VLAN 1 (for Printers and wireless access points distributed around the building).
Partly i'm doing this in the hope that maybe some helpful soul can make some sense of it, but also just the fact of writing it down MAY firm it up in my head somewhat
Thanks in advance!

Ok so - i gave up at 2am this morning, and going back to it with a fresh head! Here's the situation as it has unfolded...
I have configured up 4 of my vlans for the purpose of testing, so you'll note there are a few missing.
I have moved the Native to VLAN 11 because the ESW's were doing something weird, and wouldn't allow me to do anything with trunking... If anyone can see a MUCH easier way of doing this, please feel free to chime in!
Primarily my question though is - why isn't DHCP working? Do I need to configure DHCP relaying on the ESW switches? Or should the DHCP REQ be passed across the entire vlan back to the 3750 regardless. And if I do need to configure relaying on the ESW - how?
In my server room I have a 3750 and a bunch of servers.
One of these servers - 172.17.10.229 is a win 2k3 dhcp server (physical not virtualised)
On my dhcp server I have configured scopes for each vlan (not superscoped)
My servers are sitting on the first 16 ports of said 3750. I have set their ports to native vlan 11 and allow vlans 1-3 and 11.
My ESW switches are on ports 46, 47 and 48. Likewise, their native has been moved to vlan11 and allowed vlans 1-3 and 11.
My ESW switches have been moved to native vlan11 and trunked each of their port 48's to allow all vlans.
Test 1: Unmodified port #10 on ESW1 (default vlan 11).
Connect DHCP device.
IP address assigned from vlan 11: 172.17.10.101.
Can ping all VLAN interface addresses.
Test 2: Modified port #11 on ESW1 (VLAN 2).
Connect DHCP device.
No IP address assigned.
Set static IP address 10.0.2.55/24.
Can ping all VLAN interfaces, DHCP server, entire network.
Change IP address of test device to 172.17.10.102 for testing.
No ICMP responses from anywhere - this is good!
So as you can see i've done my homework - well most of it obviously. Because it still isn't working
Here's the config of the 3750, the ESWs of course are a bit harder to just post my config, but the general state is something like this...
ESW Switch 1
Native VLAN 11
IP Address:     172.17.8.101 255.255.252.0

Difference between Trunk links and port channel

Hi
Can anyone please explain me the difference between the Trunk links and Ether channel ?

As the other posters have already described, in Cisco parlance, a "trunk" is a link that carries VLAN tagged frames. (Note, Cisco has two technologies for these, ISL [old/proprietary] and IEEE 802.1Q [vendor independent].) An Etherchannel (also called a port-channel) is one logical link that includes one or more physical links. (Note, although Etherchannel can run across just one link, normally more than one link is configured. Older and most Cisco implementations support up to 8 links in one channel bundle. There's also multiple Cisco technologies that support Etherchannels, such as manual/PAgP[Cisco/old]/LACP[IEEE 802.3ad].)
Trunk links might also be configured on an Etherchannel link.

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

How do I get the IP address off my 3 esw 540's they are already bolted up and mounted?

New IT Manager, prior IT staff did not document anything I have identified all routers and switches so far except the 3 ESW 540's throughout the building the issue is they are already bolted up in place and in use I cannot find a console port and need the ip addresses to add them to my Configuration Professional Community.

Hello,
There are a few ways we may be able to locate the IP for those switches.
The easiest option would be to download and install Cisco FindIT, that does work with the ESWs, assuming Bonjour hasn't been disabled on them.
That however only seems to work if you are in the same subnet as the management IP of the switch, I tested it a bit here in my lab.
You can also try getting into another Cisco device that is connected to those ESWs and try looking at the CDP neighbors, although I am not sure this would show you the management IP address (it does not on SG200s, although I do remember seeing that before on some Catalysts)
Another option would be to use some sort of IP scanner, but again that depends on you being in the correct VLAN when you run the scan. You may also need to know the MAC address of the switch to make this useful.
One other thing to note is that the ESWs do not support CCP. They use a similar but different program called CCA (Cisco Configuration Assistant). This may also be able to discover the device for you, but one again you would probably need to be in the management VLAN.
Having said all of that, your best bet may be to just get a console cable in there somehow. It is on the back of the switch, on the opposite side from the power cable. It is not a console port like on the enterprise switches, but rather a standard serial port. Of course, you will still need to know the username and password to get into them, so you may end up having to reset the switch to factory defaults regardless.
Hope that helps, and good luck getting into them,

New UC560 and 3 ESW-540-24P Switches, best way to wire them

We are installing a UC560 and 3 ESW-540-24P switches at a client in a couple of weeks. I have installed many of these but have never installed one with multiple switches. What is the best way to connect these together physically. They will be all in the same rack. Was just wondering the best way to "series" the switches together and what ports to plug them into. Any suggestions would be appreciated.

There is a Smart Design: Implementation Guide at :http://www.cisco.com/web/partners/sell/smb/tools_and_resources/smart_business_comm_system.html
Implementation Guide
Smart Business Communications System 2.0 – Implementation Guide
The implementation guide complements the SBCS 2.0 Design Guide through the detailed guidance for SBCS 2.0 based Main Office deployment. This document leverages the GUI configuration capability with easy-to-follow step-by-step network deployment guidance using CCA v2.2. It also includes an installation checklist to assist during the installation process. It is recommended that users refer to the SBCS 2.0 Design Guide for underlying design guidance and considerations.
In this (figure 6) it shows a 48 and a 24 port switch connecting to each of the UC560 expansion ports (there are 2 GE ports for expansion on the 560).
These could also be 2 48 port switches (96 total ports). (In your scenario, I would connect 2 this way and the third to one of those 2.)

Esw-540-48 - direclty connected to port 34, still no MAC in ARP table

Hi all,
I have a ESW-540-48 with firmware 2.1.21 (latest)
I have the strangest problem: I can 't find the MAC address of a computer plugged directly on the switch in the ARP table.
I'm trying to search by MAC address, and also by port .
If I reboot the switch, it does work as expected.
Do you think it is software related, and in this case is there anything planned to solve this problem ?
Or maybe I should just replace my hardware ?
Thanks

Hi Firco, it may be possible it is a smart port issue. The ESW switches are very particular to use the correct smart port roles for the connecting devices. I don't think a hardware replacement is warranted unless the given ports absolutely failed to forward.
As a secondary thought, it could also be a spanning tree issue. Ensure you're using RSTP and/or the host ports have port fast enabled. If using classic spanning tree it takes nearly a minute for a port to go to forwarding state. You can disable spanning tree on the port for testing to quickly rule that out.

Help Please! Setting up SNMP on a ESW 540 48 port switch

Hi There! This is my first post and I have no idea what I am doing when it comes to SNMP. We are trying to evaluate our network performance, so we have downloaded a copy of Solarwind’s Orion and installed it on a server. The topology is as follows.
A SBS 2003 R2 Server running normal programs. A second Server 2003 R2( IP 1.2.3.4) running a proprietary program for the business and, hopefully, Orion soon. The two servers and about 20 XP professional workstations are connected to the esw 540 48 port. An uplink is attached to a consumer grade Linksys that has 5 workstations attached. I was told to install SNMP on the workstations behind the Linksys, so I did with the community name = public, Rights = Read Only, and Accept packets from these hosts = localhost and server 1.2.3.4
I am wondering what configuration I need to do (it is confusing to me) through the cisco web application to set up the switch so that it will communicate with server 1.2.3.4 and the Orion program. We may switch programs in the future (we are not tied to Orion), but it is what we have to set up the switch with. I am mainly looking for network throughput information and usage.
There are just so many options. Any help would be appreciated…. eric

Are you trying to use 2 wireless routers in the network?

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.

ESW 540 switch issue

Hello,
I have a ESW 540 48 port gigiabit switch. We have had it a year and a half. In the past year it has experienced this cycle of problems:
After a reset, within a week the fans are on full blast. Within less than a month the webgui is gone - not accessable. the switch will still switch, but to do anything to it means it has to be reset completely.
I cannot figure out how to call Cisco support for this, it has a 5 yr warranty which we are well within. I am ok with the hardware replacement but cannot figure out how to arraign that. the Support for cisco is not they type of support structure i am used to, in some cases it talks about contracts but then I cannot find prices or even how it works.
any advice? am i just looking in the wrong places for support or does cisco operate on a diffent model than other tech companies (like Apple or HP) i just am wondering if i should adjust my expectations to less?
yes i am a bit frustrated, i went out on a limb with going to Cisco for the 'best' and our other switch a 520 is also having problems
our old netgear switches worked great for about 5 years until i felt we need to improve them.
please help a clueless IT guy out

VLAN ESW-540

Hi,
I have a new switch ESW-540 24-port, I upgrade firmware to 2.1.19.
I build 2 VLAN for 2 networks: VLAN 2 and VLAN 3 . I don't use the default VLAN 1.
This is my configuration:
port e1 and e2 : ACCESS PORT on UNTTAGGED VLAN 2
port e3 and e4 : ACCESS PORT on UNTTAGGED VLAN 3
port e1,e2,e3,e4: EXCLUDED VLAN 1
port e24: TRUNK PORT with UNTAGGED VLAN 1 and TAGGED VLAN 2 and VLAN 3
Communication (ping) between e1 and e2 --> OK
Communication (ping) between e3 and e4 --> OK
Communication (ping) between e1,e2 and e24 --> NOK :-(
Communication (ping) between e3,e4 and e24 --> NOK :-(
Communication (ping) between e5,e6,e7,.... (VLAN1) and e24 --> OK
Communication (ping) between e5,e6,e7,.... (VLAN1) and VLAN2, VLAN3 --> NOK - It's correct.
Any special configuration on e24 trunk port ????
Can you help me ???
Thanks,

Hi Albert,
Bit concerned about your testing process. You have proved that untagged switch ports in vlan 1 can communicate with e24. that makes perfect sense.
What what are you using (connected on e24 ) to check for tagged packets egressing out of E24 from PCs connected on vlan 2 and vlan 3. This testing device you are using must be vlan aware.
The switch port 24 must be connected to a VLAN aware router or layer 3 switch that is trunked for ;
vlan1 untagged
vlan2 and vlan3 tagged.
So that routing can occur between vlans.

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-540-24

Dear Support Team,
What is the max power consumption of switches
ESW-540-24
Br,

As of 22-Mar-2010, the ESW 500 series data-sheet and lack of a power-calculator still fails to meet the needs of installers who need to consider the power-draw and heat dissipation of the switches from the perspective of UPS and heat management.
The main shortcoming is that under the "Power" section, it just says "24- and 48-port models: 100-240V 47-63 Hz, internal, universal;" This information isn't much use for even the simplest of calculations. More usefully, it would provide a Volt-Amp (VA) rating. One could then apply a rough-and-ready power-factor (60% according to UPS vendors), to get W = 0.6 * x VA for power needs, and W = 0.6 * (input VA - PoE VA) for heat needs (since the PoE wattage is mostly dissipated away from the swtich).
Happily, this thread provides the kind of raw information which the Cisco 'classic' power calculator is probably built from. But it's still a real hassle that I had to go Googling for it instead of finding even the basics on the data-sheet, where it belongs.

ESW 540 Combo Ports

Hello,
I am interesting what Combo ports mean in ESW 540 which has 4 SFP? Can I use 4 optic SFP at the same time(or 1000BaseT SFP) ??

Hi Kristijan,
Just out of interest, are you using firmware version 2.1.19 on the switch, your switch may be using an older version of the firmware ?
But there should be no reason why the switch interfaces 11,12,23,24 could not be placed in access mode, seems a bit weird.
I believe, if you check the VLAN interfaces, vlan1 should still be untagged on those "trunked" ports.
So, please check the firmware version, but the ESW is covered by a great Warranty, so if you are still having issues, call the Small Business Support Center (SBSC) and allow them to share your screen via webex and resolve your configuration issue one way or the other.
