Cisco Switching/Routing :: 3750X / 6509 - Trunking Over Single Mode Fiber

Oct 26, 2011

I'm having a problem with some new gear and can't seem to figure it out.  I have a 3750X-48P-S with a C3KX-10G-NM using SFP-10G-LR transceivers and I'm trying to trunk that with a 6509 that has a X2-10G-LR transceiver over single mode fiber.  This is not working.  Cisco TAC says the SFP+'s that we just got brand new are both bad and we need to order new ones.  I find that hard to believe but who knows.
 
The switch recognized the module and I tested all 4 ports in gigabit mode using GLC-SX-MM transceivers, all worked great.  I have the SFP+'s in tengig1/1/1 and 1/1/2 as they should be.  There are no other SFP's in the module either.
 
When I do a sho int tengig1/1/1 and 1/1/2 the media type doesn't show the transceiver that is installed like it does for the GLC-SX-MM ones.  Maybe it's not supposed to or maybe it just doesn't recognize them and it's a hardware issue.

Cisco Switching/Routing :: Nexus 4000 Won't Connect To 6509?

Sep 12, 2011

we have a new IBM Bladechassie with two Cisco nexus 4001i switches.I have configured one external port on each nexus and connected them to a cisco 6509 with 1G cisco SFP-modules and MM fibre.Both the nexus and 6509 ports are configured as trunk ports, and set speed to 1000.I see light in the SFP-modules on both devices, and through the fibre. When I connect the devices, the link doesn't come up. No light on the ports, the nexus says "link not connected", and the 6509 says "notconnect". I have tried reconfiguring the ports in many ways, even as accessports, nothing seems to work. If I move the SFP and fibre from the 6509 over to a trunk port on a cisco c2960-24TC-L, the link comes up and everything is working fine. why this work on a 2960 and not my 6509 coreswitch? One of the configs I've tried on the 6509:interface GigabitEthernet2/20description *IBM Bladechassie 2 NW1*switchportswitchport trunk encapsulation dot1qswitchport trunk native vlan 34switchport trunk allowed vlan 34switchport mode trunkend

Cisco Switching/Routing :: Nexus 5548 And 6509 VPC Connectivity?

Nov 12, 2012

We have two 5548 switches connected to a pair of 6509 running in VSS mode. I am trying to understand the benefit of having bridge assurance on the uplink ports.
 
If we have the command spanning-tree port type network enabled we cannot do a non disruptive upgrade. If there is bridge assurance on the uplink it warns you of this. Yet if I do not run bridge assurance on the uplinks I can do a upgrade without any disruption.
 
Why in god would I enable bridge assurance on this VPC link if I cannot do a non disruptive upgrade?

Cisco Switching/Routing :: 6509 - Nexus And Span Sessions

Oct 24, 2011

I am in the early planning stages for a 6509 to Nexus 7K migration. Based on my experience with the 7K's at a previous company where we ran into a lot of issues, I am trying to be very careful.
 
I am more at home with the 6500 chassis and know what I can do with them.  I remember running into a limitation on the Nexus that involved their not supporting span sessions like the 6500's do.  Is that still the case ? 
 
If that isnt an option in the short term, I will need to look at a substantial investment in ethernet tap's to replace the lost span functionality because the security group's heavy use of span sessions.

Cisco Switching/Routing :: 6509 - Load Balancing Nexus Switches

Jan 24, 2013

I am trying to understand what load balancing method is used on a port channel on a Nexus switch . I have a server connected by a VPC to two Nexus switches. The nexus switches are only acting as layer 2 switches. I have a 6509 connected via a upstream link that does all of the routing for my VLANS. If  have a server connected to the Nexus switches and it talks to a server on my 6509 what load balancing happens on the Nexus going across VPC 27 which is a layer 2 trunk going up to my 6509. Is it done on layer 2 or layer 3 flows?
 
My Nexus shows the default load balancing configurations
 
Port Channel Load-Balancing Configuration:System: source-dest-ip
Port Channel Load-Balancing Addresses Used Per-Protocol:Non-IP: source-dest-macIP: source-dest-ip source-dest-mac

Cisco Switching/Routing :: 6509 - Nexus Dual Homing With N2000

Oct 24, 2011

I am trying to work up a config based on equipment that was ordered before I joined my current employer.
 
I will be deploying N2Ks at the top of each rack.  Each N2K will be dual homed to two different N5K's. Being new to the Nexus, I understand that the N2K's have no brains and are dependent on the N5K's they connected to. Wasnt sure how to tell each 5K that the 2K that was dual connected to it needed to be able to move between N5K's based on failure/availability. I havent been able to find a sample config of what this will look like anywhere on the Nexus section of the Cisco site.
 
The next step after this will be to connect N5K_1 to blade on a 6509 and N5K_2 to a different blade on the same 6509.  I will be installing two of the 10Gig blades in the 6509. Havent been able to find any sample configs on what this would look like either.  We are upgrading the sup engines on the 6509 to the new 2T version.

Cisco Switching/Routing :: 6509 - Nexus 7009 Rack Concerns

Mar 5, 2013

I wanted to know if any has the Nexus 7009 chassis installed into a 600 wide rack with the sides fitted and if they are experiencing heat issues? 
 
My client will be replacing their aging 6509 chassis with 7009 devices, but the physicals dont tally with the install guidelines for the 7009 series chassis.  The current install of the 6509s does not tally with the recommended install guidelines for those either, but they have not expereienced any heat issues...
 
The 7009 will be fitted with 2xSUP2E, 3x48portSFP-F2E cards and 2x10GSFP-M2 cards with 2x6K PSUs.  I am genuinely concerned they may cook these devices, but space restrictions look like vetoing the upgrade to 800 wide racks.  Likewise moving to 7010 chassis may prove tricky due to existing other installs within the racks limiting vertical space.

Cisco Switching/Routing :: Console Authorization On Nexus 7000 Switch Not Working?

Nov 29, 2011

i'm trying to enable command authorization for ssh as  well as console access to a Nexus 7010 box (version 5.0). Following is  the config:
 
aaa group server tacacs+ ACS5-1
    server 10.12.19.11
    server 10.12.19.12
    source-interface loopback0
snmp-server enable traps aaa server-state-change
aaa authentication login default group ACS5-1 local

[code]....
 
As  you can see, the default group configuration ACS5-1 for authenticatoin  has applied to both defaults and console. But the command authorization  does not appear to be applied to the console. As a result, when i login  from the console and get authenticated, the command authorization does  not trigger and i can run commands I'm not supposed to. In the  configuration, I do not see "aaa authorization console" option unlike we  have in IOS.

Cisco Switching/Routing :: Nexus 5548UP Change Peer Keep Alive Link

Apr 19, 2013

I have a pair of Nexus 5548UPs that have some high priority servers running on them.  Servers are ESX hosts running Nexus 1000v's.  Each host has multple connections in a VPC to both 5548s.  We have been having intermittant ping loss and slowness of traffic to the VM's on these hosts.  I was poking around trying to figure out what the issue could be and found that the peer-keepalive command was not set to send the heart beat across the mgmt0 interface.  I would like to change this to point it accross the mgmt0 interface. Any tips or advice for me on making this change with production servers running on the switches?  I do not want to cause any loss to any systems when I make this change.

Cisco Switching/Routing :: Nexus 5ks Connected To 6513s - Peer Link Active?

Mar 13, 2013

how the Nexus 5500s work ?currently we have two 6513 Core switches  6513-1 and 6513-2 running HSRP and RSTP.  6513-1 is currently the Root Bridge, 6513-2 is setup as our secondary root.  We also have two 5548UPs setup with a peerlink between them.    Picture attached. "Current Setup.jpg"
 
There is a 20gig port channel between the 6513s and also a 20gig port channel(peer link) between the 5548s. 5548-1 has a 10g fiber running back to 6513-1 and 5548-2 has a 10g fiber running back to 6513-2.  Currently now Spanning tree is blocking the link from 6513-2 going to 5548-2 which is what we expect.  We were working on moving some things to different racks the other day and moved switch 5548-2 to another rack and brought it back online without the peerlink fiber connected. We started to have issues and tried to plug the peer link back up, but still continued to have issues.  We started to troubleshoot and noticed that both 5548s were acting like the master of the VPC domain and was not letting traffic pass accross the Peer Link.  We then rebooted the 5548-2 with the thought that it would come back up as the secondary in the VPC domain.  When it finally finished booting back up it then caused a huge loop in our network accross both uplinks to the 6513s and the 5548s peer link which in turn took our network down.  Spanning tree did not work like it was suppose to and block the port going from 6513-2 to 5548-2 in time.
 
My thought was this didn't seem like a good setup.  I went to the drawing board and decided we needed to have an uplink from both 5548-1 and 5548-2 going to 6513-1 setup as a port channel/VPC and also a uplink from 5548-1 and 5548-2 going to 6513-2 setup as a port channel/VPC.  Picture Attached. "NewSetup.jpg"  We are also planning on buying a "2K-C2224TP-1GE" to hang off the 5548s to use for ethernet.
 
how the Nexus 5ks work and haven't done a lot of research on them. Would this not be a better setup since both switches will have an active link to the root bridge?  The links from the 5548s going to 6513-2 should always be in a block state until we loose both uplinks to 6513-1 or the entire switch itself correct?  Also how will the 5548s reactive if I was to loose the Peer link fiber?  Will they continue to work as normal?  When it looses this Peer Link does it suspend all the VPCs for the servers on the secondary switch in the Domain so the network doesn't get confused on which link to send traffic up since there isn't a peer link active or is this not the case?  Also with the peer link down will the 6513-1 know which 5548 to send the traffic to if there is only 1 device (not setup in a VPC) on one of the 5548s?  What are your recommendations/best practice on the setup for the 2k?
