Guys, Regarding Content Delivery Networks Architecture With regards to the CDE 205 (CDSM). Is there a way where we can initiate automated database backups? thanks!

Hi, I'm wondering if anyone has encountered a similar issue and if there is a way to resolve this. We are conducting tests around BGP link failure detection on the uBR10k/SIP-600/10GigE SPA where it is taking around 8-9 seconds to detect the fibres being pulled from the transceiver. Is there an option to speed this up? thanks!

echelon360 · ‎06-09-2009

thanks Giuseppe! Appreciate your responses. I had a look in detail on this and from what i understand, i think it requires the TurboACL feature to be enabled (access-list compiled) before it is active on the router. http://www.cisco.com/en/US/docs/ios/security/command/reference/sec_a2.html#wp1061456

Hi, ISR 2811 I have several ACLs running on this router. Is there a way i can gather stats to see how much of resources the router is assigning to these ACLs? thanks!

thanks Giuseppe!

Thanks Giuseppe! I have updated the test topology and included what i think will ensure tests for ethernet module stress test and ACL limitations. Pls let me know your thoughts Ethernet Module example port 1 ixia (6/4) ------ (192.168.4.0/24) define stream on 6/4 >destination ip as 192.168.3.1 C3750 ----- -configure routed port connecting to 2811 >ip add:192.168.100.1 -static route >ip route 192.168.3.1 255.255.255.255 192.168.100.2 2811 ---- -create SVI 100 (connection bet 2811 and C3750) >int vlan 100 (192.168.100.2) -static route >ip route 192.168.4.1 255.255.255.255 192168.100.1 ixia (6/3) ---------- (192.168.3.0/24) define stream -destination ip as 192.168.4.1 **i'm not sure if the Fa0/0 of the 2811 back to Ixia would pose as a bottleneck. ACL Test -------- i will need to specify ACLs on a per SVI basis. Hence, i would need to setup additional static routes to point traffic to an SVI then onto the Ixia subnet to provide for data traffic. Then include ACLs deny statements to match this traffic. Would this approach be suitable? Pls let me know your thoughts

thanks Giuseppe! How can i improve this setup on port 6/4. Have this port connect to another port of the 3750 as well? I will need to test out ACL limitations on the 2811 ethernet module and hence, i believe i will need to have each of the 9 port on an individual vlan then configure respective SVI to allow for the ACLs. Pls let me know your thoughts.

Hi, I need to setup a 3750 and a 3845 in the same vlan for a test. I'm thinking the only thing i need to do is to configure a subinterface on the 3845. Pls advice i'm missing something impt 3750 ------- interface gi1/0/5 switchport access vlan 20 3845 ------ interface gi0/0.20 encapsulation dot1q 20

Hi, Can someone with ixia experience pls advice how best to perform this test? Attached is the test setup. I'm trying to use ixia to generate packets to flood the ethernet module of the router. -should i have each of the 3750<>2811 ports be setup with individual vlans? -how do i define a closed loop traffic from an ixia perspective. If i were to use port 6/4, how do i configure ixia to treat this port as "closed traffic port"

hello rajeev, Nortel uses MLT for etherchannel configs. have a look at page 329 of the attached doc. HTH

Try leaving the speed as 100 but duplex as auto

echelon360 · ‎04-07-2009

Hello Giuseppe, thanks for responding. I was looking through the ixia docs and the best approach to take is to assign each port to a vlan and have a stream assigned to it. the link between ixia and the 3750 is a trunk fibre port. Let me look more into this and try the configurations.

echelon360 · ‎04-02-2009

Hello Giuseppe, I have setup the test build as attached in this message.Could you please advice if i'm approaching this correctly. -cabled up 9 LAN cables between the 3750 and 2811 -created vlan 900 on both switch and router. Assigned all ports to this vlan I'm stuck with the Ixia part of it as i'm not entirely sure how to proceed. Should i create 9 flows based on the number of ports connected?

Hi all, I'm trying to setup a packet flow between Host A and B using netperf but i am unable to generate the packet. I think i'm missing something with the translate statements. Please advice if the statements i have are not correct. (pls reference diagram) *DNS routing for X25 Router A --------- TCP to X25 translate tcp 192.168.1.13 4000 x25 0404456368002 X25-TCP translate x25 0404456368005 printer 192.168.1.1 port 4000 Router B -------- TCP to X25 translate tcp 192.168.2.13 4000 x25 0404456368005 X25 to TCP translate x25 0404456368002 printer tcp 192.168.2.1 port 4000

Hello Giuseppe, just a quick qtn pls. I'm setting up the cabling now and at present, i've connected 16 ports from the 3750 to the 3845 (NM-16ESW). Is there a significant difference if i test using a single broadcast domain as opposed to having ports configured as native ports and flooding traffic via independent broadcast domains?
