I have two MLS conected by 2 fast ethernet links f0/11 and f0/12 on both sides.I am trying to set up a layer 3 etherchannel using these two links . But when i see etherchannel summary, they dont show up as layer 3. Instead they show as layer 2.

Is it possible to to build a Layer 3 ether channel from two separate physical switches (layer3) that are trunked together?I know you can easily do this on a single switch and on stacked switches which I've done but in this case the customer have purchased two 3560X's which are not stackable yet want redundancy. The purpose of the etherchannel is to connect both switches to a private circuit provided by the hosted partner then route to the same setup in the DR location to different subnets.

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.

I need to build a layer 2 etherchannel on a Cisco 3560X. Now the question:
¿ May I instruct the switch to inspect the outgoing ethernet packets for IP information and therefore execute Layer 3 load balancing on this portchannel regardless of the fact that this will be a plain Layer 2 etherchannel? (for example: port-channel load-balance src-dst-ip)
The documentation does not say that this is not allowed, so in principle it seems to be that it would be feasible.
As we know there are three layer in cisco Network Model:
-Core
-Distribution
-Access
So my question is in Core / Distribution layer should i use Etherchannel between switches or use Stacking if switches are stackble.For ex: suppose I have two cisco 3750 switches . so should i use etherchannel between them or use stacking in core layer?What are the advantages and disadv of both.
Ether 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 want to setup VLAN with the switches SG300 and SLM2024. What is the suggestion to connect these 2 switches. We have the Juniper net screen.

Switches are
WS-C3750G-24TS-E1U
WS-C3750V2-24PS-S
I have configured a vlan interface on a 3750 switch. there is aprox 4Mb active traffic flowing through the interface, but when I do a "show interface vlan (vlanid)" the output show zero bits in and zero bits out. Its a typical L3 config with one IP on the vllan interface acting as the gateway for the VLAN devices. Is this a normal behaviur ? and if so is there any way to get the traffic in/out stats. The end PC/devices are connected to this switch via an L2 TRUNK and I dont have access to the L2 switch on which the actual devices connect. so cant get the real time stats of those interfaces.

View 2 Replies View RelatedWhen you configure an ABR to inject a summary route into an area, what are the circumstances under which the ABR will inject the summary? I.e., since it's not a set of specific subnets learned directly from other OSPF routers, does the summary get injected regardless of what's in the routing table of the ABR?
I would imagine this could cause problems in a situation where there is an ABR injecting a large summary into an NSSA that also has a backup path over the Internet (IPsec tunnel or something). For example, if the area 0 routers from which the ABR receives routes went down, the ABR would continue to inject the summary route into the NSSA thus tricking those routers into sending traffic to the ABR rather than over the backup link.
I can't imagine any other way an ABR would decide when it's suitable to inject the summary though.

View 2 Replies View RelatedIn earlier versions of LMS it was possible to choose i.e. the Routers category (top level) and enter a series of commands to be excluded from the comparison. In LMS 4.0.1 I experience, in several different installations, that this is not possible. It seems I can enter one exclude command beyond the defaults per category, the rest is not applied even though the feedback from the application is positive. Next time I access the Exclude Commands view, the commands I entered are gone. Is this a change of behaviour or a bug?
View 2 Replies View RelatedI have a layer 3 switch with a bunch of SVIs all in the 192.168.x.0/24 range. I just want to advertise a 192.168.0.0/16 summary to the BGP neighbors. I can do this either by:
1) Redistributing connected into BGP and then using the 'aggregate-address' command to advertise the summary.
2) Specifying a network statement in the BGP config for every single SVI, then using the 'aggregate-address' command.
3) Create a static route to null0 (ip route 192.168.0.0 255.255.0.0 null0) and put 'network 192.168.0.0 mask 255.255.0.0' command in the BGP config.All three fulfill the same purpose of summarizing all the SVIs, but creating the static route is much cleaner in this case. It seems like the aggregate-address command is mostly intended for routers that are aggregating connections coming from other routers and all of them share a common prefix.
if I can do the following deployment using a Cisco ASA5510 security plus.
At this moment I have two interfaces in use one (outside) with the IP: 172.16.21.254/24 and the other (inside) with the IP: 192.168.4.1/24. Now the customer needs to connect another network that works with the IP segment: 192.168.0.0/22.
The IP segment 192.168.0.0/22 goes from 192.168.0.1 to 192.168.3.254 that means that there is no a overlap with the network segment 192.168.4.0/24. My question is: If I configure another interface in the ASA that works in the segment 192.168.0.0/22 the routing table will auto-summary the network and merge it with the network 192.168.4.0 or will it leave the networks apart??
I don't user dynamic routing protocols but I cannot do the changes if I have doubts because the network 192.168.0.0/22 is a the Network for the Factory Automation Systems.
My Cisco 3900 router is not taking the no auto summary command?
