Cisco Switching/Routing :: Throughput 3560 Versus 2951
Oct 29, 2012I see the throughput of a ISR is 296.96 Mbps how would this compare to a 3560 if the figure is 38.7Mpps?
What would the throughput of a 3560 be in Mbps?

Cisco Switching/Routing :: Ip Sla Differences Between 2960S Versus 3560?
May 16, 2013We replaced a 3560 with a new 2960S and I'm only able to configure a single ip sla where before we had three ip sla entries on the 3560. Obviously, one is a L2 switch and the other a L3 switch. This is an expected difference between switches, correct?

Sep 26, 2011We are planning on testing a new ISP provider in our company but we have the following doubt: This new provider is using a Optical Fiber line (GPON – PT Prime) for this new internet connection and we already have a Cisco RV220W router but they are not sure if that can be used, so they just informed that they a capable router is the Cisco 2951-SEC/K9, that they are selling of course. So our actual doubt is if the Cisco 2951-SEC/K9 can have some “extra” WAN configurations/authentications that are not available in our Cisco RV220W and that can implicate that we cannot use our RV220w router?

Cisco Switching/Routing :: 3750 - L2 Trunking Versus L3 Switching
Dec 9, 2011some of our switches have the switchport mode trunk command configured between the 3750 switches but other 3750 switches connected to our 6509 core switch do not have the switchport mode trunk command to permit Vlans from going across the swtiches instead it has an ip address and says no switchport what is the difference between does two. Is trunking used only for Layer 2 and L3 is used to route interface vlans?

I have got queries on the below issues:Which model of Router can support upto 2Gig's of WAN Internet connection running BGP? Any list of routers and switches supporting variety of throughput's from 1 MB to 1 GB.I have heard some experts stating "Switches don't have throughput concerns as they switch the traffic and don't need to route traffic" How true is the statement?? and if it is, Why do we require 6500's instead of 3560 Distribution Switches.

I want the ports to act similiarly to the ports on an 881 router - where I assign the VLANs on the router and I set the VLANs to the switchport interfaces.I would like to be able to create the VLANs on the router portion of the 2951 and then, enter the switch module and configure the Ports to the VLANs but, how do I logically connect router to the switch? Is it an internal logical interface - meaning how are the VLANs getting from the router to the switch?

Cisco Switching/Routing :: 892W / LAN Versus WAN Ethernet
Feb 14, 2012I own a Cisco 892W router. The router has 2 WAN ports and 8 switch ports. Now I know -
-WAN ports can create sub interfaces, assigne IPs, cannot be assigned to a VLAN - sounds very much like a routing port. (sh interface gives - Hardware is PQII_PRO_UEC)
-Switch ports are for VLAN assignment, trunking, IP assigment etc,. (sh interface gives Hardware is Fast Ethernet)
I know they are different but at the same time confuced what the difference are? I also know on some 3xxx series switchs you could say "no switchport" and translate a switch port to a layer 3 port. But on 892W you can't do this? Struggeling to understand the difference.

View 2 Replies View RelatedCisco Switching/Routing :: Ghost Multicast Versus 3750G
Feb 13, 2013I manage a network with a ghost server, a 3750G, several outside access, and some vlans.This is a very simplify view of this network:
The ghost server is on all vlans connected to a trunk port on the 3750G which is used as a central switch and for basic routing.All equipements connected to vlans 1, 2 or 3 are on 2950 switchs themselves connected to the 3750G on dedicated access ports, each in there respective vlans.
All equipements connected to vlans 1, 2 or 3 have as gateway a vlan interface on the 3750. (10.0.x.3)All the vlan interfaces have route-maps applied on them to redirect traffic to their dedicated outside access.The route-maps match only traffic destinated to the outside.
Everthing is working well but the multicast.When I create a ghost session on the server, I can see computer connecting on it, but the multicast never start.If I use directed broadcast it works with good perfs, but the CPU processes of the 3750 go high because of the IP Input (Till 99%).If I remove the route map from the vlan interface which is on the ghosted network, the multicast works but with poor perfs.If I shutdown the vlan interface the multicast works well with good perfs.
It seems my problems are tied with the Vlan interfaces but I don't know why.
This is a sample of the config:
switch 1 provision ws-c3750g-24ts-1u
system mtu routing 1500
vtp domain SM
vtp mode transparent

Cisco Switching/Routing :: IGMP On 6500 Versus 4500
Mar 11, 2012I encountered a problem migrating configuration from Cisco 4500 with IOS 12.2(53)SG4 to Cisco 6500-VSS with IOS 12.2(33)SXI7.
With 4500, we had 2 servers with JBoss running multicast to build up the cluster. They used 239.X.X.X multicast IP. There was no need to configure "ip igmp snooping vlan XX static XXXX.XXXX.XXXX interface X" neither static arp entry.
When we migrated to 6500 in VSS, we had to do:
mac-address-table static XXXX.XXXX.XXXX vlan XX interface X disable-snooping
With this command, the JBoss cluster worked well. The question is, ¿Is there any difference regarding IGMP in 4500 versus 6500?

Cisco Switching/Routing :: Throughput Of Etherchannel On 3560G
Nov 27, 2012We have a problem with the throughput over etherchannel in LACP with 2 or 4 ports. It is iSCSI traffic (vmware esxi 4.1 U3) is going from 2 separate NICs (ports) to the etherchannel (with 2 or 4 ports) that has a SAN connected (Nexenta).
The SAN is configured in passive LACP and the switch is in active LACP. Actually it does not matter if we do LACP or just MODE ON, still same result: ~1GBit/s throughtput in either direction. Like already mentioned, 2 or 4 ports in the etherchannel make no difference, or the configuration of the etherchannel.
I will post some config data below, but here is the question: Why can't we see traffic beyond 1GBit/s? Source and destination are capable of doing much more than that (vmware esxi RAID 5 of 1TB SATA; SAN 16 x 1TB NL-SAS). If we look with CNA, we can see that the traffic is balanced equally over the etherchannel ports. With or without QOS or flowcontrol, no difference. This whole traffic happenes on this switch.

I saw a few things that seemed to be in favor of a Layer 3 switch vs. a Layer 2 switch. Some items like better performance due to switching based on IP vs. switching based on MAC. Some information that will show the 3850 to be a better choice or that the 2960 is capable.

View 15 Replies View RelatedCisco Switching/Routing :: 5020 - Slow Throughput Between Two VLANs
Feb 14, 2012When transferring traffic between two VLANs my throughput rate seems to drop to about 1.5 - 3.0 megabits / second.
My setup is like this...
Two Nexus 5020 switches. (switch01 and switch02)
Two Nexus 2232PP fabric extender switches. (switch03 and switch04)
Two Dell R815s with Chelsio and Intel NICs. (host1 and host2)
The servers run Xenserver 6.0, but as part of testing with this I've tried installing RedHat 6.2, VMware ESX 5.0 (vsphere 5).
The issue occurs when using trunking and transferring data from one VLAN to another. Example...
VM1 is in VLAN401 with an IP address of 10.100.40.40. The VM is on Host1. VM2 is in VLAN402 with an IP address of 10.100.50.50. The VM is on Host2.
I've been using a network throughput tool called iPerf to test and I find that I can only get a throughput rate of about 3.0megabits.
If I switch VM2 to be in VLAN401 with an IP address of 10.100.40.41 I get a throughput rate of about 6.7gigabits/sec.
In the above scenario, I'm using a Layer3 interface on the Nexus 5020, but in production we use a Vyatta virtual firewall.
I worked with Citrix for about 3 months and that was a dead end.
Cisco Switching/Routing :: SGE2010 - Slow Gigabit Throughput?
May 4, 2010I realize this is just a small business switch, basically a rebranded Linksys, but why I'm only getting 200Mbits/s
- 48 port - 10/100/1000 , set to standalone mode
- 3 separate PCs on this switch , all are fast machines with Core 2 duo / plenty of RAM etc...
- all 3 auto-sense 1Gbps connection
I use iperf tool for bandwidth testing and no matter which PC I pick as server, which as client I get about 150 to 250Mbits/s
I am not looking for full 1000 here, but 200 seems rather sad....
- jumbo frames seem to make no difference
- I am using TCP test in iperf , standard no extra flags , 10 seconds, 20 seconds or even 30 seconds all come out the same.
- wiring is shady as some of it is just Cat5 , but when going from one laptop on the switch to another with brand new Cat6 cables I STILL only got 200.
Cisco Switching/Routing :: 2950 - IPERF Throughput Comparison
Mar 2, 2012I am currently using catalyst 4506 L3 switch and 2950 L2 switches for pc's which are EOL. I am replacing L3 with 3750X, two switches in a stack. L2 is 2960S all with gbps ports. I have to have a baseline (performance comparison with the current setup and new setup) and I am using the following methods
1. Iperf throughput comparison among local vlans
2. Iperf throughput comparison with remote data centers servers.
3. Ping/ftp upload/download comparison with remote DC's. FTP file is around 3GB.
Today I have tested the above with the new setup and compared it with the old setup. For the tasks 1 & 3 I found better performance with the new setup. However the task 2 did not show any performance increase infact the throughput was much lower comparing to the old setup.
