Cisco Switching/Routing :: 3560 Topology In Packet Tracer Related To Etherchannel Configuration
May 23, 2012
i have made a topology in packet tracer related to etherchannel configuration.i am using 2 3560 switches and 1 2950 switch. Now what i want is to bundle up the redundant links between these 3 switches. The links fa0/1-3 between 2950_1 and 3560_1 switches have been bundled up but when i try to bundle the links fa0/4-6 of 3560_1 to fa0/4-6 of 3560_2 it wont work. i am using channel-group 1 mode desirable between the 3560 switches. secondly if i want to assign ip to port channels then it has to be of same subnet between 2 3560 switches right and it must be same between 2950_1 and 3560_1. But these 2 subnets should be different from one another.

I been practicing with the configuration of layer 3 etherchannel configuration and i am facing a problem here. I have two 3560 switches and i want a layr 3 ether channel configuration setup between the first 2 ports of bothe the switches. I assign IPs to the Port-channel 1 of both the switches "10.1.1.1 /24 and 10.1.1.2 /24" but i am unable to get a successful ping. what am i doing wrong. below are the configs for bothe of my switches.
3560_1
Building configuration...
Current configuration : 1274 bytes

Is it possible to have ether-channel across 2 switches? As an example, having a server with 2 ports connect, 1 port to Switch-A and the other to Switch-B and then use those two links on the sepatate switches but to the same server to form an Etherchannel.
The Switch-A and Switch-B are 3560 series

I am using 3560.IP rouitng is being turned off on this.Curious to know if I will create etherchannel or port channel.I think etherchannel.Correct me if I am wrong.On connecting switches I have vlan10,20,30 to be allowed.I am sure I need to allow these all vlan in 10,20,30 which are on the trunk port on each side switch.Post that will add channel-port lacp and make it in active mode.Is that correct.This way traffic will be load-balanced/aggregated on minimum 2 ports who are the part of this.

I'm configuring two etherchannel groups (2 ports in each) on a 3560 switch. I need to trunk multiple vlans over each channel group.
I created the vlan trunks and allowed vlans on each physical interface. I notice that I can also configure the vlan trunks on the port-channel interfaces that were created. Should I configure them under those interfaces, or leave them on the physical interfaces? Relevant config is below:
interface Port-channel1
!
interface Port-channel2

I have Cisco 3560x layer 3, but there is one problem with MAC ACL. Here is sample scenario:
I have two V LANS 2 & 3. There is one device (D1) on V LAN 2 and three (D2,D3,D4) devices on V LAN 3. D1 can talk only to D2 and D3. D4 can talk only to D2 and D3. D1 and D4 cannot talk at all. I got the IP access list all set, but I was asked to get the MAC ACL on it. The problem is that as soon as packet is routed, its MAC addresses will change, correct? Is there way of preventing device with same IP but different MAC from talking to device it should not to, keeping in mind that the packet will be routed?

here is result
2 Po2(SD) LACP Fa1/0/15(I) Fa2/0/15(I)
Both ports are up up but standalone Int port channel 2 is down down.Need to know if this is default behaviour when we config etherchannel between stack switches?

I am installing a several new Cisco VM servers. The VM hosts are losing connectivity when we apply the etherchannel config in the core stack. VMware has stated that the etherchannel load balance needs to be src-dst-ip in order for the etherchannel to work.However, my current stack has 2 etherchannels configured to other switches through out the bldg in network closets. The current load balance configuration is src-mac.My question....when I make the change to src-dst-ip, will my network connectivity go down? I saw there was an older article on this that doesnt provide an answer just a work around. Here is the article. [URL].

I'm trying to set up a network comprised of three LANs connected by serial. As this is a small part of an assignment I've been instructed to subnet into /26 and to use /30 subnets for my serial connections.At the moment I can ping between devices on each of the LANs but I can't ping between routers at all. Embarrassingly I'm not sure why, I think it may be something I've missed on setting up the serial links as I have set routers up fine before using other connection types.

I'm preparing myself for CCNA exam and i started doing a lot of different examples. I've got problem with Packet Tracer when i'm trying to apply some security settings for the range of switch ports in default VLAN 1. I might just demonstrate my commands so it will be easier do understand.

I have been playing around with Packet Tracer trying to understand EIGRP and to put it into practice. Well im not doing so well, I cant get the routers to form an adjacency therefore nothing is pinging outside of the routers. [URL]

I'm an IT student and I've been assigned with homework simulating a network including an ISA server and some clients in Packet Tracer but I can't find anything which can be configured like an ISA (Internet Security and Acceleration) server(this is kind of Microsoft's technology as I know) in Packet Tracer, the generic Server from the devices box has only some basic services such as HTTP, DHCP, DNS, FTP, AAA, ... but none of anything related to ISA, all the servers in Packet Tracer have only 1 interface whereas the ISA server (as far as I know) should have at least two interfaces, and there is also no CLI supported for those servers so I think I can't simulate ISA server in Packet Tracer, can I?

I'm trying to create a silent, scripted install of Cisco Packet Tracer 5.33. At the end of the install there is a box that comes up about Packet Tracer Skills Based Assessment (PTSBA). Is there a way to supress this dialogue box? I'm using "PacketTracer533_setup.exe" /sp- /verysilent /norestart" with no luck.

I am unable to get traffic from any VLAN to communicate outside of the router, as well as get any traffic from outside of the router to communicate with any device on either VLAN. I am able to ping the router from each device on each VLAN, and vice versa. However, the traffic seems to die at the router, and I cannot figure out why. I know it's probably a small, easy fix, but I cannot seem to find any kind of documentation on it.

I have 2 locations, at a distance of 600KM.These two locations are well connected by Point to Point L2 VLAN with a speed of 2 MBPS and supported by CISCO 3560G switches.Location A has a VLAN to communicate to the other VLAN at Location B. Location B has also got 3 VLANS which are inter connected with Location A.Now the hardware in one of VLANs in Location B has moved to Location A for obvious reasons.
For further refernce am giving the VLAN IP address here....
Location A
VLAN1 for communicatng to Location B
IP Range 172.20.44.210
Subnet Mask 255.255.255.0
Default Gateway 172.20.44.210
VLAN2 for the desktops in Location A
IP Range 192.193.194.1-255
Subnet Mask 255.255.255.0
Default Gateway 192.193.194.1

I have a 3560 switch with 1 VLAN (VLAN 10) where I need to make ports:
1-10 as isolated (can't contact each other)
11-20 as community (need to contact each other like a normal VLAN)
23 as promiscuous (server that ports 1-20 need to get to)
24 as promiscuous (WAN router where ports 1-20 need to get to and the remote servers).

A client of ours has installed an SG300-24P switch and would like to setup a LAG between the SG300 and the 3560 switch we manage for them. They would like the LAG to also pass the voice and two data VLANs currently in use; 5, 10, and 100 respectively. I configured the two ports as an Etherchannel with trunking on the logical port, but no luck. I reconfigured as follows:
interface GigabitEthernet0/1
switchport trunk encapsulation dot1q
switchport mode trunk
channel-group 1 mode active
end
[code]....
I see no output when I do show lacp nei. At this point the client is looking to use for the configurations to use as he does not know how to setup the SG300 and it is a switch I have never dealt with. I have found some configurations that I believe would allow a single VLAN across, but nothing I believe will allow the LAG to pass all the VLAN's.
