I'm have ether channel between CISCO 6506 and CISCO 3750X. I'm set load-balance ip-src from 6506 side and dst-ip from 3750 side. i'm try test etherchannel for detect physical link for test ip. On 3750 all work, but on 6506 i'm get error: test etherchannel load-balance interface port-channel 1 ip 10.10.10.2 10.10.10.1 ^ % Invalid input detected at '^' marker.
View 1 RepliesEther channel: Cisco documents say Cisco uses proprietary hashing algorithm to compute a binary pattern that selects a link in the bundle. For example below a 2961 router with a switch module " NM-16ESW" performs" XOR" operation to compute the binary value to select a link.
R1#show ether channel load-balance Po1 ---> Source XOR Destination IP address.
1)Would you guys share the output " show ether channel load-balance" on your platforms?( i just want to see how different platform support different algorithm besides xor). Layer 3 ether channel on a sw.
On router, we first create ether channel and then assign int into port channel. Suppose we have a layer 3 switch and we want to put ports f1/1-2 in port channel 1. Can i configure like this: sw(con) int range f1/1-2 no switch port
channel-group 1 mode desirable. Or we must create a port channel just like we do on router and then assign ports to port channel?
Backbone fast: Suppose we have a switch with three ports, f1/1.f1/2.f1/3.
f1/1 ( root port)
f1/2( blocking)
f1/3 ( designated port).
Backbone fast is enabled on our network. Suppose sw receives a inferior bpdu on its current root port f1/1. Sw sends out RLQ on its designated port(f1/2) and Blocked port (f1/3). Suppose sw receives the rlq reply on its designated port ( f1/2). What will sw do? Will it expire the max-age timer on its root port ( f1/1) or will sw wait for all the rlq responses then expire the max-age timer on its root port ( f1/1) ?
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 setting up a lot of small remote sites that are only reachable via VHF ethernet radios that operate at 32k. I'm going to be using 2 of these radios shooting to two seperate base station radios to provide diversity. I'm going to have a Cisco 1941 sitting between the two radios and the way I have it configured now is to only use one radio and the second is only sitting there in case the primary fails. I was thinking though that I could load balance them to give a little more throughput. The devices at these sites are really low speed but we like to use snmp to monitor everything that is ethernet so I wanted to give as much bandwidth as I can.
Will load balancing work in this situation? What would the basic configuration be? This is all internal to our network so there are no ISPs to deal with. We're using C1900-UNIVERSALK9-M IOS will that work or will I need to change that?
We have to cisco WS-C4900M with Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500e-IPBASE-M), Version 12.2(53)SG5, RELEASE SOFTWARE (fc1).We have four gigabit link connected between those two switches.We have create a LACP port channel with those four ports on both switches. Ether-channel is up and running and defined with a load-balancing method of src-dst-ip.But when we test the load-balancing, it's not using the src-dst-ip rule with the XOR: [code]
View 5 Replies View RelatedI have probem with symmetric load balancig, in case when both ends of ether channel are on the sam switch (we are using VLAN translation).We need to create L2 port channel with both ends on same switch (Cisco WS-C4500X-24X-ES), for example:Po1 – Gi0/1, Gi0/3 (one end of port channel )Po2 – Gi0/2, Gi0/4 (other end of port channel)On ports in Po2 we will configure VLAN mapping.My question is what is the best ether-channel load-balancing scheme with wich we can accomplish full symmetry in both directions? For example, if traffic in one direction goes through Gi0/1 (member of Po1), in other direction also must go through Gi0/1. This is required because we need to connect four appliances for DPI (they are full L2 transparent) and traffic through each appliance need to be symmetric.
I can set-up src-ip, dst-ip, src-dst-ip etc. load balancing, but, actually I need src-ip on Po1 and dst-ip on Po2. Is there any way to set up different load balancing mechanism for different ether channel on same switch (4500X).
Is it possible to use two different load balancing methods at each end of a port-channel between two switches?
We have a Cisco 6509 at one end of the port-channel and a Cisco blade switch 3020 at the other end. Right now, we are using "src-dst-ip" at both end of the port-channel. We would like to change this. That is, we would like the #3020 switch to use "src-dst-ip" while the 6509 switch should use the "src-dst-port".
Why we want to do this, the reason is that we have FWSMs on the 6509. I've read that by configuring "src-dst-port" on the 6509, one can get a better performance of traffic going through the FWSM. However, the issue is that the 3020 switch does not support "src-dst-port".
Will there be some pause in traffic on formed ether channel interfaces (4500E switch), when i will change the default ether channel load balancing method to src-dst-port (or any other non-default method)?
View 1 Replies View RelatedWhat is the best way to load balance traffic between an FWSM and ASA 5520? Both are attached to a 6509-E (in seperate VLANs). The problem is the FWSM doesn't support any dynamic routing protocols (in multi context mode). So with my limited knowledge I don't see a way to do this.

View 1 Replies View RelatedI have problem with VPN and Load Balance at the same time.VPN (Gateway to Gateway) between two RV042 routers is working fine with only one WAN or two WAN's with Smart Link Backup. If i switch to Load Balance communication through VPN is almost impossible.
I have postgres server (port 5432) in first location and clients in another. Clients cannot connect to server or lose connection after while. This is example, but every communicaton except ICMP over VPN with Load Balance enabled is faulty (file sharing, RDP...). Everything works fine using public IP and port forwarding or VPN with only one WAN.
If i understand it correctly Protocol Binding should affect only "normal" communication (outside of VPN), but it looks like VPN communication is also divided between WAN1 and WAN2. Of course this cannot work this way because VPN works only with one WAN.
Another question - is it possible to bind communication TO selected target port with RV042 Load Balancing to selected WAN?

Latency shoots up from 10 to 200. QoS goes to ****. And I only need 0.50-1Mbps to keep a steady online play. This was the problem with my 2Wire. So does the 2640B load balance the bandwidth?our max speed is 3.5Mbps according to the ATT Rep.

We want to us an ISA570 and load balance between two isp connections, two of our switches will be standalones and not connected to one another. One switch will be for data and another VOIP/Data. The ISA will also do NAT and we need to make sure that the VOIP network can get out to the first isp. I assume we will need a static route for that to make sure it goes out the right isp. I just don't know if routing mode needs to be enabled in order to specify a static route, because I heard you can't have NAT and do routing mode at the same time.

What might be the default gateway?Can i create a serverfarm with two rserver with different subnets?
I configured a RV042 to load balance 2 WANs. It appears to working well but I would like a 2nd opinion as to whether or not I chose the proper settings to accomplish the task.
1. WAN1(ISP1) is the existing internet connection(1.5mb T1). I have a block of static IPs with ISP1.
2. I added ISP2 to the RV042's WAN2 connection to increase bandwith (10mb). I only have one static IP on ISP2.
3. I want everyone on this router to use WAN2... well... almost everyone... for the most part.
4. I want to keep WAN1 active on this router because there will be periodic inbound connections using static IPs (from ISP1) that are setup with one-to-one NAT. I also have a voicemail system that needs to continue to use ISP1's email relay (SMTP,25).
Anyway, I was able get the outgoing traffic that had to remain on WAN1 working with protocol binding. In order to get the router to use WAN2 for pretty much everything else, I set it for load balancing and set "Max. Bandwidth provided by ISP" for WAN1 up & down kbits/sec both to 32 (very low). I left the WAN2 up & down settings to the actual speed of WAN2.
The result is very low traffic on WAN1 and lots of traffic on WAN2 which is what I wanted. Did I do this right? Is there another preferred method to accomplish this.

Have two ACE 4710 in HA setup. We would like to setup HTTPS loadbalance(actually just a primary and standby configuration in the serverfarm).

I thought that maybe both interfaces would traffic about 450MB.Is there some wrong configuration with the load-balance command?. At this moment there is no load-balance, It is only configured the port channel with the default configuration.
