I have a 7K running 6.1 code, on F series line cards. I need to set it to prioritise DSCP EF marked traffic, that's all at this stage, but am unclear on the configuration steps required. The packets will already be marked, I just need to ensure they end up in a priority queue.

View 4 Replies View RelatedI am trying to add WCCP to be configured for websense. My first option seems to be either purchase an IPServices license for the stack of 3750E switches, but i am thinking this will require us to license all three switches in the stack. The second option i am looking at is to do the WCCP configuration on the 2800 router we have on the edge. The problem is both Gig ports are in use, one going to the firewall and the second going to the ISP. My first question would be, which option is better in terms of manging as well as cost of implementing it.The second question is, if WCCP on the router is a better option, what is the add on module i should be looking to get to add the additional ports to hook up the Websense cache.

I am trying to install SFP-GE-T module on Nexus 5548UP Switch, but is giving the ‘SFP validation Failed’ error. The details of the switch is given below
Model : N5K-C5548UP-FA
The interface is configured with speed 1000 before inserting the module, still we are getting the same error. PFA logs for more details We have 8 Nos of SFP-GE-T modules , all are giving same error. We tried to insert the module on onboard as well as expansion module.
The same module is working fine on Cisco 3750X-24T-L Switch As per the Hardware installation guide , SFP-GE-T transciever is supported on N5K platform. Please extend your support in configuring SFP-GE-T module on N5K platform? We tried with SFP-GE-S module on the same switch , and the same is found working fine.
We are working with a contractor to upgrade our network, and I heard from them that the 5596/5548 might not need the Layer 3 module for our inter-VLAN routhing. They have yet to give me an answer.
We do have a few static routes on our current layer-3, core switch too.
I am having trouble updating the epld image on the 10gb Module of Nexus 7k. we have two nexus and two 10gb module. Tried the other one and it worked fine. its jsut the first one that has problems with the epld image. i have tried on both the nexus on two different slots and still the same error.
I get the following error:
Chain connectivity is broken while upgrading the FPGA. (Error Number : 36)
Trying to find some documentation as to whether there are any other steps for inserting this new module in our N7K. We have 2 blades in already and 2 Sups in 5 & 6. I'm assuming its like the 6500s, where we just slide it in and the OS configures the global parms for it and the default VLAN.
View 2 Replies View RelatedWe are looking forward to implement IBM BladeCentre Swiches connectivity with Nexus 2k module.I would like to brief you about my network over as follows:
Coreswitch : 6513 ( Layer 3 switch + Spanning Tree root)
Nexus 5010 : Layer 2 switch
Nexus 2k 10G ports based module.
Currentl Solution : we want to connect the IBM Blade Switches (4) as demonstrated in the attached diagram which will be connected to Nexus 2k module as Ether-channel Access port.
Initially we been proposed by our vendor with this design and Now vendor is recommending us to connect the Blade switch etiher to Nexus 5k switch or directly to 6513 core-switches instead of Nexus 2k modules as they say Nexus 2k modules are only to connect the Edge devices .
We do not have ports available on Nexus 5010 to connect the cables from IBM Blade Centre Switches. Otherthan that, incase if we go ahead and connect the IBM Blade switches as access ether-channel access port with Nexus 2k module what are consequences we have to face realted Spanning tree or any other.
One of our Nexus 7000 modules failed and generated the status below. Could this possibly be a hardware issue?

we installed copper and fiber sfp modules in the 2232PP and none would link up. we pulled the sfp modules out and entered the speed 1000 command and re-inserted the module with no success. the same sfp modules works fine in every other cisco device. we must be missing something. running latest nx-os software.

View 4 Replies View RelatedI want to prioritize egress voice traffic across a trunk terminated on an F1 module, N7K-F132XP-15. I am unsure about the setup; according to the "show interface capabilities" F1 interfaces support 8 egress queues, while the Nexus QoS documentation provides configuration referencing 4 queues. In addition, I am not clear about the relevance of network-qos on F1 queueing setup.

how we can enable multicast on the Nexus 7000 switches in the simplest form so this will continue operating.
We are currently using two Nexus 5548UP's as our Datacenter Network Core. I have a pretty simple objective: I would like to enable Jumbo Frames on a single VLAN only(VLAN 65). This VLAN is used strictly for backups. I do not want to enable Jumbo Frames on the other VLANs(VLANs 1-10). Im not sure what the best way to do this is.....or if it is even possible but I am hoping to get some configuration examples.

I need to trust and prioritize voip traffic on my 6509 core
at the moment I have mls qos trust dscp on the interface
Is this enough? or do I need to enable the priority queue? how do i do this ? as it doesnt accept the priority queue out command like a normal switch
Recently we will add 2 new core Switch 3750X, these 2 equipments will manage the spanning tree ( root)my idea is to change the priority in order to make 1 or the 2 of them the root, my question is if i setup the same priority for both when one go down the other will assume the role of root in the spanning tree topology ?

View 1 Replies View RelatedAfter opening up Solarwinds NPM, I noticed that a few of my interfaces had lots of discards (who knows how long it's been sets the counters were reset)

I'm not the best in the world when it comes to QoS, we do have some VoIP phones, but they are only a specific network, and do not travel outside, since there are used mainly for VoIP training. I do know both interfaces are running the default of FIFO.
May I know how to manually set the priority (root ID and bridge ID priority) and for spanning tree? Which one should I use based on the command below? and how does it affect the path cost of it?

I have a Cisco Catalyst 2960 with IOS Release12.2(53)SE (because of a contract I can not update it) -> the release notes for this version describe the following:
When auto-QoS is enabled on the switch, priority queuing is not enabled. Instead, the switch uses shaped round robin (SRR) as the queuing mechanism. The auto-QoS feature is designed on each platform based on the feature set and hardware limitations, and the queuing mechanism supported on each platform might be different. There is no workaround. (CSCee22591)
My config is as follows:
interface FastEthernet0/1 switchport access vlan 200 switchport mode access srr-queue bandwidth share 10 10 60 20 priority-queue out mls qos trust dscp auto qos voip trust no cdp enable network-policy 1 spanning-tree portfastMy question now is:When the priority queue is not enabled with auto-qos because of the software bug is it nevertheless enabled with the additional priority-queue out command?
I am getting ready to make changes to our spanning-tree configuration in the data center. In familiarizing myself with the network I noticed that our core switch (6509) wasnt the spanning-tree root for the datacenter.
When I enter the spanning-tree priority command on the central 6509, will it be a hitless change (i.e. will there be any disruption to the network) ? All switches are connected to the core/central 6509 by a direct connection.
I know that when I change from pvst to rapid-pvst that the network will bounce because of the change in configurations to all of the switches.
i have a 3560 connecting to a sp with limited bandwidth. i have one interface on the switch whose traffic i do not want to drop. i want this traffic to go into the high priority queue. i am not sure how this should be configured, but here is my best guess and my current qos configuration on the switch:
qos map cos-dscp 0 8 16 26 32 46 48 56
mls qos srr-queue output cos-map queue 1 threshold 3 5
mls qos srr-queue output cos-map queue 2 threshold 1 4 6 7
mls qos srr-queue output cos-map queue 2 threshold 2 3(code)
since cos 5 is mapped to dscp 46 then this traffic would go into the priority queue. is this correct ?
