Hello, I would like to ask if someone has ever configured an etherchannel that interfaces resides on different cards with different per module load balancing mechanism. We are planning to have such a case as we will implement MGSCP solution that requires for egress traffic per source ip load balance and for ingress per destination ip load balance. The existing devices hold an etherchannel that the interfaces that it bundles are connected to different modules. 7600-1 module 1 int g1/1 ------7600-2 module 1 int g1/1 7600-1 module 3 int g3/1 ------7600-2 module 3 int g3/1 We are planning to change the load balancing mechanism on module 1 per source ip and for module 3 per destination ip. Will this change result something bad to the existing operation of the port-channel? The only thing that i can think is some underutilized links. BR Kanellos ... View more

Hi all, We experiencing a problem with quotas when we change package to a subscriber. We are having the Unprovisioned package that doesn;t allow any other kind of traffic except the redirection of browsing traffic to a portal. Also we have configured quota consumption for that traffic. We don't have a SM and QM but a third party external PCRF server that perform these tasks. We have also configured the provisioned package that the subscriber has internet access but we count his quota with a different quota profile. The problem that we have is when the subscriber has quota and the quota depleted we don;t get a Quota restore message for the quotas that the subscriber must have. As an example the subscriber is in the unprovisioned package with the quota bucket 2 and he has 20 MB. When the subscriber is in provisioned package and he buys 50MB service and when the quota depleted message comes he changes to package unprovisioned. The problem that we have is that we don;t have a quota restore message in order to take the quota value of unprovisioned package and as a result the subscriber doesn;t have service even to this package. My question is why we don;t have the quota restore message during this change. 2012-04-01 14:05:05 | INFO  | CPU #000 | EM Agent: login operation was called with parameters: ID: xxx, mappings: ip add , additive: false, policy: packageId=8 2012-04-01 14:05:05 | INFO  | CPU #000 | EM Agent: quotaUpdate operation was called with parameters: ID: xxx, quota: 1=20480:1 2012-04-01 14:05:11 | INFO  | CPU #000 | EM Agent: quotaStatusIndication operation was called with parameters: ID: xxx, quota: 9,2,1333278311,2=10861 2012-04-01 14:05:43 | INFO  | CPU #000 | EM Agent: quotaBelowThresholdIndication operation was called with parameters:  operation with parameters ID:xxx, quota: 8,-1,1333278343,1=0 2012-04-01 14:05:43 | INFO  | CPU #000 | EM Agent: quotaDepletedIndication operation was called with parameters: ID: xxx, quota: 8,-1,1333278343,1=0 2012-04-01 14:05:43 | INFO  | CPU #000 | EM Agent: quotaUpdate operation was called with parameters: ID: xxx, quota: 1=0:0 2012-04-01 14:05:43 | INFO  | CPU #000 | EM Agent: quotaUpdate operation was called with parameters: ID: xxx, quota: 1=0:1 2012-04-01 14:05:44 | INFO  | CPU #000 | EM Agent: login operation was called with parameters: ID:xxx7, mappings: ip add, additive: false, policy: packageId=9 2012-04-01 14:05:47 | INFO  | CPU #000 | EM Agent: quotaStatusIndication operation was called with parameters: ID: xxx, quota: 8,2,1333278347,1=0 2012-04-01 14:06:05 | INFO  | CPU #000 | EM Agent: quotaBelowThresholdIndication operation was called with parameters:  operation with parameters ID: xxx, quota: 9,-1,1333278353,2=0 Thanks ...

At instances as soon as traffic appears in a new subscriber session the SCE issues QuotaRestore (as expected) but also QuotaBelowThreshold with QuotaDepleted almost simultaneously, disregarding a grace period of 5 sec that the SCE is supposed to wait before complaining about the quotas (as we have configured on Quotas Settings section). This phenomenon appears a couple of times and not every day. This problem is appeared moreover in the subscibers that are having few quotas. For an example the subscriber that has only 50MB and something like this happens then all the quotas disappear. The step of quota consuming is 50 MB. For subscribers that are having more quotas there is no problem because the quota update is repeated. I forgot to mention that we have external quota mechanism and we connect with SCE subscriber API. It is no clear how quota mechanism works. BR Kanellos ... View more

Hi all I would like to ask if would it be a problem to use two LEGs (radius sniffer and radius listener) in order to obtain the framed-route and the frame-ip-address attributes for the same user in the same radius packet? The number of subscribers is expected to be around 500000 and we have two servers in veritas cluster for SM. The subscribers will be served by four SCEs 8000. We confirmed that we could have the expected result by we are concerned for the capability of the SM and SCE to handle all these customers. I have not seen documented somthing that it is analogous to this and i am not sure if it is proposed by Cisco. BR Kanellos ... View more

Hello I am testing the case of periodically redirection of a subscriber by the SCE. This is the case that our customer wants to implement, but during the tests that i am having i can not understand how it works. This is the result of the abnormal behavior that redirection has. The requirement is to redirect the subscriber every 24 hours when he clicks or browses to a new site. In my tests i decrease the time to 6 minutes and what i see is that every time that a subscriber comes to the network he redirected to the specific URL. But there is no periodically redirection when the time period of 6 minutes exceeds. It doesn't follow that rule, but it performs the redirection in a random way after the time period of 6 minutes. Additionally if you can clarify what is the p_numOfRedirections that appears in the show command, sh party name 192.168.2.123@test.. Thanks in advance Kanellos ... View more

We decided to implement the 1+1 cascaded topology with two SCEs 2020 and we realized that many strange things happen. The first and more important broblem was when the primary SCE recovers from a failure it immediately takes again the role of primary, but it does not have any data in its database with the result to lose all the existing quotas and information for the subscribers as we work in push mode with the API-SM. For this reason we opened a case to cisco TAC and the answer is that is the normal behavior of the cascaded topology when the option in a case of failure is cutoff. Something that is nowhere documented and especially in the chapter of faiure scenarios in the SCE configuration. Also is strange to me that it is documented a feature that you have the chioce to put the SCE that comes from a failure to non operational mode, but it doesn't also work again in this configuration (cutoff in a failure). The answer of the TAC is to use the bypass mode, but what can you do if this is a requirement of the customer?  You have to redesign in order to be addressed with the customer needs (the MGSCP configuration it would be applicable, but it needs time and testing with the other components of the solution). I don't know what is your opinion but i believe that is unacceptable answer for the reason that first the documentation was so poor for this kind of topology and second there was not only one feature that it doesn't work but two (the first was with the empty database when the primary recovers and the second was with the choice to becaome this SCE nonoperational when it recovers). I would accept that the first might be the way that this topology works, but the second is a configuration option that is not supported. I documented my experience in this community in order to avoid engineers to use the 1+1 cascade topology of SCEs and to express my disappoitment in the way that Cisco handles this case.
