Cisco Switching/Routing :: ISRG2 Runs Out Of Memory

Sep 5, 2012

ISRG2  (c2951-universalk9-mz.SPA.152-4.M1.bin) has 512 MB of DRAM. Periodically it runs out of memory: [code]
 
 1. Why "show process mean" command shows less memory than 512 MB? Processor Pool (248 MB) + I/O Pool (58 MB) ~ 310 MB only?
 
2. *Init* process holds more memory than normal (202 MB). What may cause this?

Cisco Switching/Routing :: Does 2691 Router Supports 3 - WIC-1DSU-T1- Cards

Dec 20, 2011

My 2691 Router has already 2 serial cards WIC-1DSU-T1 installed, When i install the 3rd serial card and reboot the router, it detects the 3rd card  installed but 3rd card has no light.
 
When i do sh ver  it shows 3 cards installed.
 
When i install this 3rd serial card to other Router  then light shows on card and it works fine
 
So i am thinking if 2691 Router only supports 2 serial cards?

Cisco Switching/Routing :: 2811 High CPU And Low Throughput

Aug 10, 2011

I am facing a problem on a 2811 router. The CPU is remaining around 60% and the router throughput is reaching at most 18 MB while according to the data sheet the 2811 maximum throughput is 61MB. I have checked the output interpreter in order to try and figure out the cause of the high CPU and to determine if it is affecting throughput but there are not processes consuming more than 10%. I have attached the show tech-support and the show process cpu history outputs.

Cisco Switching/Routing :: 1905 What Is Throughput Of A Router

May 24, 2013

I have found recently that Cisco 1905 router is having a throughput of only 10 Mb. But the router is having 2 Gig ports!.My understanding is that throughput is the data packetforwarding done by a router at a time.
 
What is actually mean by throughput of a router. How the router can handle 1 Gb of data from interfaces at a time?

Cisco Switching/Routing :: Throughput Of Etherchannel On 3560G

Nov 27, 2012

We 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.

Cisco Switching/Routing :: Finding Switch That Supports 4096 Multicast Groups

Jul 10, 2012

Any switch that supports 4096 multicast groups?I am working on a system that includes over a dozen catalyst 2960 switches.  The customer has pointed out the 2960 switch does not satisfy the requirement to support 4096 multicast groups (even though it is more than adequate for the number of active multicast groups).  It looks like the 3560 supports more multicast groups than the 2960, but is still far less than the requirement.

Cisco Switching/Routing :: Slow Throughput Between 3750 Etherchannel

Cisco Switching/Routing :: 5020 - Slow Throughput Between Two VLANs

Feb 14, 2012

When 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, 2010

I 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, 2012

I 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.

Cisco Switching/Routing :: 3750 / 2950 - Which Series Switch Supports Vlan Up To 4000

Nov 4, 2012

we are using 3750 and 2950 switches  both of them do not support vlan up to 4000 .we need vlan about 3000 .Whic cisco series switch do support  vlan up to 4000.
  
2950
S-SW1.3(config-vlan)#exi

Proposed configuration has too many VLANs for this platform. Reduce the number of VLANs proposed.

S-SW1.3(config)#end 
 3750
SW1(config-vlan)#exi

proposed configuration exceeds the limit of 1005 VLANs that can be supported on this platform. Reduce the number of VLANs proposed to be within this limit.

Cisco Switching/Routing :: ASA 5520 - NAT Capable Device With High Throughput

Jan 26, 2012

I'll have to replace an old WS-C3550-24. Reasons for this: EOL/EOS & we'll need a NAT capable device...
 
As I understood, the only L3 catalyst that is able to perform NAT is a 6500? Is that correct? If the above is correct, it seems I can only replace the setup by using a router/ASA with a L2 switch. A router with high throughput (+/- 300Mbps) is hard to find, especially as NAT will require CPU resources...
 
So, my best (affordable price) solution is getting an ASA5520 (450Mbps FW throughput) and a L2 switch?

Cisco Switching/Routing :: 1921 - Router Recommendation Based On WAN Throughput

May 21, 2013

I'm trying to identify a Cisco router that will give 300+Mbps through a 1Gb WAN port.  I think the 1921 can get up to around 300Mbps with the on board RJ45 ports, but are there any other/better suitable models?
 
There's no need for any other particular functionality or feature set, the routers aren't doing anything fancy or unusual - it's the achieved throughput that's important.

Cisco Switching/Routing :: 3750G - Maximum Throughput Reduced By Stacking Or Any Of Other Features

Mar 21, 2012

We are experiencing output drops on our 3750G-12S (IOS 12.2.55).
 
I have monitored throughput with MRTG, but it doesn't seem that high compared to that the 3750G is supposed to handle 17.8 Mpps.
 
The 3750G's are stacked, running ospf, qos, multicast (IPTV) and etherchannel.Is the maximum throughput reduced by stacking or any of the other features?
 
I don't know if one can estimate what the maximum throughput is per ASIC or per port, but on one of the ASICs that is having drops the peak unicast load is 1.3 Mpps and multicast Mpps is 0.9 Mpps. Total ~2.2 Mpps.
 
This doesn't seem high at all and I don't understand why the drops are appearing. What I can do to find out the reason for these drops?

Cisco Switching/Routing :: 2911 With IOS Version Is 15.1 - Routing Table Not Updating

Oct 2, 2012

I am using Cisco 2911 & IOS version is 15.1. My problem is that after some days (e.g. 15-20 days), the routing table suddenly stops updating & then I have to enter the default route again to make it up. I am using Track 1 to track default route here. After primary link goes down, the Track is also going down but after coming the primary link up, the track is not coming up. So, I have to add the default route again to make it up.
