Cisco 7600, SCE8000, Etherchannel

I have two Cisco 7600 and 4 Cisco SCE8000.
I try connect two 7600 through etherchannel with sce.
I read MGSCP design guide and configured src-ip load-balance on one 7600 and dst-ip on another 7600.
I tested by test etherchannel load-balance command, IPs are use same interfaces on etherchannels.
But I see all numbers of sessions on each SCE but not 1/4 of all sessions.
What may be wrong in configuration?

After I wrote to config Cisco SM command force_subscriber_on_one_sce=true and restarted SM, I have 100% control CPU utilization on SCE and high CPU utilization of SM server.

Cisco 7600 in MPLS

Hello,
1)
I have a question regarding Cisco 7600/6500 ( sup720 exactely) in MPLS.
I've read in documentation and also in some forum posts that "show mpls cef" is not MPLS aware command and should be used only for IP traffic. But still in some Cisco documents you can find that it is recommended on Cisco 7600/6500 for MPLS to use show mls cef instead of show ip cef (wether it is P or PE device in MPLS).
Does anyone know what is true?
2)
Also when load balancing is involved in MPLS with Cisco 7600/6500 (sup720)
P=======PE (P and PE are 7600 and there are two paralle link with the same cost between them).
In documentation can be found that in MPLS, CEF is still in charge for load sharing (src-dst IP header based) except for hardware based platforms.
Since 7600 is hardware based platform does it have some other load sharing method or it is also CEF based?
Thanks in advance.
Regards,
A.

Hi Prima,
This question has been already answered several times and the answer is still the same :-) : it's not supported on 7600 platform due to hardware limitation.

Configuring SYNCE/PTP on Cisco 7600 and Cisco MWR for NSN NodeB

Hi to All,
I would to ask for support on how i can establish the PTP between Cisco MWR 2941-DC and a NSN NodeB. The Cisco MWR is connected to a Cisco 7600 with SPA-2X1GE-SYNCE where the SSU/OSN clock is connected on the BITS ports. Hope you can assist me with the configurations.
Thanks,
Eugene

Dear Genedeath,
I have noticed that you posted this message since last year ..... have you ever been able to solve the case??
I had a glance to the diagram and it looks quite similar to my case.
I need to configure a Cisco MWR2941 for the very first time in order to support SyncE for packet Abis between a NSN FlexyBSC and a NSN BTS.
BTS---------------Gig x/y MWR Gig x/x-----------------------FlexyBSC
I guess the source clock would be provided by BSC...
Can you support me according to your experience ??
thanks and regards!

Cisco 7600 Series Ethernet Services cards types & queue values

Hello,
There is different types for the Cisco 7600 Series Ethernet Services cards.
( More expensive cards with high queue values and less expensive cards with
low queue values.)
http://www.cisco.com/en/US/prod/collateral/routers/ps368/data_sheet_c78-549419.html
Hardware queues
ES Plus XT 40G line cards
• 128,000 ingress queues
• 256,000 egress queues
ES Plus XT 20G line cards
*• 64,000 ingress queues*
• 128,000 egress queues
Hierarchical QoS (H-QoS)
http://www.cisco.com/en/US/prod/collateral/routers/ps368/data_sheet_c78-570730.html
Hardware queues
Cisco 7600 Series ES Plus Transport 40G and 20G Line Cards
*Supporting up to 16 level 4 queues per physical port*
Hierarchical QoS (H-QoS)
Low queue cards have got only 4 queues per physical port. High queue cards
have got minimum 64.000 queue. This is very huge difference. In what kind
of scenario do we have to use the High queue cards ? Could you give some
examples please ? Kind Regards.
Burak

HI Burak,
Each time you configure a class with bandwidth allocation or shaping,.. a queue will be used so if you use such card to provide QoS for a lot of subscribers sharing the same interface, you will need a lot of them !!

Cisco 7600 MPLS and set Qos group

Hi, i'm am trying to use to following class-maps and policy maps on a Cisco 7600. The same maps have been used on both 3700 series and 7200 series. However when i try to apply IP_TO_MPLS_OUT and MPLS_TO_IP_IN on the 7600 (with SUP32 and 48 port gigabit blade) i get a message on the console
"set qos group" not supported.
I used the QoS group to carry the MPLS EXP value (as label would is popped) and this works well.
How can i get the QoS group to work on the 7600, if not is there a valid workaround?
Many thanks for your help.
policy-map IP_TO_MPLS_OUT
class qosgrp5

class qosgrp4

set mpls experimental topmost 4
class qosgrp2
bandwidth remaining percent 20
set mpls experimental topmost 2
class class-default
bandwidth remaining percent 30
random-detect
set mpls experimental topmost 1
policy-map CE_OUT

policy-map MPLS_TO_IP_IN
class MPLS_EXP5
set qos-group 5
class MPLS_EXP4
set qos-group 4
class MPLS_EXP2
set qos-group 2

Hi,
I'm not aware that you can use qos groups on c7600 (LAN ports ?).
For the MPLS_TO_IP direction you can use 'mpls propagate-cos' on the egress interface as workaround. This rewrites the egress IP ToS with the internal DSCP (which is inferred from the topmost MPLS label).
For the IP_TO_MPLS direction you could just match on the original DSCP ?
cheers,

Cisco 7600 Series can't back up it's config using Ciscoworks

We have a problem with Ciscoworks. Our client's Cisco 7600 can't back up it's configuration with Ciscoworks, while the rest of the devices can. They are all enrolled and discovered in the Ciscoworks of our client. Do you have any idea how to troubleshoot this? Thanks!

Have you partitioned the drive and formatted it Mac OS Extended (Journaled?) If not, try that and see if it helps:
Extended Hard Drive Preparation
1. Boot from your OS X Installer Disk. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

I'm uncertain, but on a 7600 with 15.x IOS, it's likely QoS is following the HQF changes, and if so, max-reserved-bandwidth has really been deprecated.

Could anyone tell me all MIB's I need to manage a Catalyst 6500/Cisco 7600? Or better, do you know any documents where I could find this information?
Thanks for your help.

You can get all these MIBs from http://www.cisco.com/public/mibs
As for what MIBs you need, it depends on what you're trying to poll.

LOAD BALANCE BEHAVIOR FOR 7600 ON ETHERCHANNELS

Hi Everyone,
Currently I'm planning to implement ether-channels on 7600 routers, but there's something that's still not clear to me, regarding the load balancing behavior, for L2VPN and L3VPN.
I've read that 7600 in MPLS default load balance behavior is to take the SIP and DIP if present and the bottom of the stack label or the 5th label depending upon the number of labels on the stack. In l2VPN scenarios when ether-channel is used, if no IP traffic is present what is the default behavior of the etherchannel to calculate the load balancing hash function to select a given link on the bundle.
I'll appreciate any feedback regarding this.

Hi Louis, you could set default routes on the ASA's with tracking, and use ospf downstream to inject the default route in to the network with default information originate - this will only advertise out a default route if it has it in the routing table. With SLA you can track internet reachability by IP SLA echo to something like 8.8.8.8. Both sides can advertise this in to the network, if one goes then there is one left. Just be mindful of the policies and NAT required, you will have to duplicate the rules on the ASA's. With the NAT you have to ensure, that outgoing traffic comes back in the same path it left so it doesn't break connections.

Cisco 7600 ES Plus Intelligent Services Gateway License-For old and new 7600-ES+20G3CXL= line card

Hi everyone
i had an one thing, that i don't understand clearly.
We had Cisco 7609-S witth 7600-ES+20G3CXL line card and Intelligent Services Gateway License (76-ES+ISG-LIC)
Now the Line card had hardware problem, and my manager not alllow me to buy services, He want to by the brandnew one.
I read some informations from cisco website " The license is purchased per chassis in increments of 8000 subscribers requiring BNG features with 8 MPLS VPNs per license".
But i don't know clearly that can we use the existing 76-ES+ISG-LIC with the New Line card? or I must buy the both of things
Anybody can support me?
Thanks

Netflow on Cisco 7600

Hi All.
It is known that SUP720-3B on Cisco 76xx doesn't support ip flow egress on interfaces.
In the last IOS in cisco feature navigator versions I see netflow egress accounting support (see picture bellow).
Somebody tested this feature? It really works?
Thanks.

Cisco 7600 under attack?

Is possible to router 7600 Sup720-10GE-3CXL , CPU goes up to 99% when under attack ?
I think we have some attack from outside and that destination ip is uplink ip of 7600 router .
Can syn packets rise cpu on 7600? Can they go to RP processor ?
somethink like this attached .

Hi,
This can be a kind of SYN flood attck. You can send this traffic to a loopback or contact your ISP and ask them to block this traffic.

Cisco 7600-es20-ge3c and Cisco ws-x6724-sfp

We have a Cisco 7606-S with the following cards installed:
7600-ES20-GE3C
WS-X6724-SFP
Aren't both of the above cards 1 gigabit line cards? What is the difference between the two cards? Not sure why we have the two different cards installed.

Hi,
The architecture is different for both the cards which make it a choice for different scenarios. For example, WS-6724 supports more on LAN related technologies supported while ES20 supports feature like EVC, label imposition etc.
In short, WS-6724 is a LAN car while ES20 is a WAN card.
A detailed explanation about the feature support will be available in datasheet.
