Cisco WAN :: Routing And Multiple Wan Uplinks On 6509E?
Mar 5, 2012
simple question regarding WAN transit uplinks on a 6509E ad BGP. The Hardware configuration is:
Cisco 6509-E Chassis with enhanced Fan
WS-SUP720-3BXL
WS-X6748-GE-TX
Dual power supply and 1 G flash for Engine
I'm currently using both 1 gig uplinks on the SUP for my two carrier transit uplinks (BGP). I would like to add a third carrier transit uplink into my BGP. Can I utilize the 6748 for access to the SUP720 routing to expand my transit carrier uplinks? Any thoughts on options without having to go to a 10gig SUP720?
I'm looking at the WS-C2960S-48TD-L and have a question about the uplink ports. Is it possible to mix 10G on one uplink and 1G on the other? The datasheet says 2x10G SFP+, 2x1G SFP so I am thinking mixing is not possible.
I currenty have a Nexus 5010 connected to a core 3750X switch stack in a VPC trunk using 2 1Gbps links. I want to move this link to 2 10Gbps links without losing connectivity. So I want remove a 1G link and move it to 10G and then once that's up move the other 1G link to 10G hopefully without losing connectivity. So the question is, can I have a 1G and 10G link between the Nexus and 3750s in the same virtual port channel without causing problems?
We are looking for some latency in our net and I am trying to check if our STP implementations is running correctly - we have a simple flat network here and no blocked ports here - just two nx 5010 which are interconnected with two uplinks.A remote site - mirrored setup - with 2 10G dark fiber connections - one for each nx5010 - is connection a DR site. I have split the two sites in two stp domains by enabling bpdu-filter on the vpc between the two sites.
I have been running wireshark on the local segment for some time and see the STP RST ROOT announcement every 2. seconds - this is probably normal ? I was looking for some alternate root negotiation packets which would cause the mac tables to be flushed.
I have a stack with 4 2960S and 4 uplinks to the core. I was wondering if it is better to connect one uplink for each switch, or just connect two switches, thus the two members (2&4) not directly connected.
I need to connect one sw3750E with two 3750X , with Uplinks at 10 GBps. My doubt is the next:
Switch 3750E has two TwinGig Adapter Converting 10 Gigabit Ethernet X2, phisically each twinGig adapter has 2 slots for SFP modules. Can I install sfp+ If I want to use copper for Uplink at 10 Gbps, I just need to install one SFP-H10GB-CU5M transceiver ???? the other SFP slot is disabled automatically?
in the other side 3750X in order to support copper at 10 Gbps a C3KX-NM-10G network module is considered, this will be connected to SW3750E by means of SFP-H10GB-CU5M.
The second 3750X will be connected to second twinGig Adapter of 3750E using another SFP-H10GB-CU5M transceiver.
I have a new 6509E with 2 sup 2T cards. The 10GE ports on both sup cards will connect to 2 5548s. Can i connect the management interface on the new 6509E to the old 6509 until i free up space to bring the line cards over?
We have configured BGP on Cisco Switch 6509E, firewall module on the switch is making nat for all users,but users is not going to internet yet, I do not know hot to configure 6509E to give internet access to users.If I route default route to FWSM,then BGP will not work? If I route default route what is the meaning of BGP then?
I do not want to write static route because BGP should work (4 ISPs redundancy)
How to let users to go out to the internet throug BGP, but nat is being done on the firewall module on 6509, routing is beiing done on 6509,to to configure it?
I have a couple of 6509-E combined in a VSS system. I need to upgrade them to support 8 (or 16 at max) 10G uplinks. I already used the two built-in VS-S720-10G fiber connectors for VSL links. Which Ethernet modules do you suggest to use? are there any related upgrades that I have to do?
I want to migrate a Cat 6503-E VSS to Cat 6509E VSS. We plan to use the same supervisor that we have on the Cat6503E, for minimizing the configuration change on the Doing this, the vss link will need to be changed, due to the fact that the supervisor slot will change with the Cat 6509, slot 5 instead of 1.
Question: is there a way to just change the vsl-link interface on a existing VSS ?
I have a pair of Core VSS 6509E SUP 2T. Two different LANs, two diff. Subnets. larger LAN has been connected to the VSS pair usng normal SVI and Post-Channles (has lots of closets 3750 stacks) and no problem. Second LAN, two closets, stacked and connected to each other via Port channel and trunk + SVI interfaces. Now, I have SVI interfaces for both LANs on teh VSS pair and that is causing traffic from one LAN to jump over to the other VLAN and rightly so because the VSS pair see both subnets as directly connected subnets. I was wondring if I delete the SVI for the second LAN and only keep the L2 VLAN this will be resolved> The reason for the second LAN to connect to the VSs pair is only that It has to go through the VSS pair to get to the WAN router (both LANs will go out through this Same WAN router) but WAN router is not my concern at this time. I need to isolate these two LANs/subnets traffic so no one VLAM traffic jumps over the other.I have also thought about VRF but at this point I am not sure if teh 3750 stacks supports VRF and if it does how to implement VRF on the second and samller LAN to just allow it go through the VSS pair in order to get to the WAn router.
I have a 6509E switch with dual 6Kw power supply that is logging "Power supply 1 input has changed. Power capacity adjusted to 2671.20W" then will bounce back to normal at random times from 1sec to 10sec. Is there a command to check what each input level of the power supply to try to identify possibly which source is causing the problem? The power supply input lights remains green while this is occuring.
Trying to find documentation on the proper procedure for installing a second sup720 into our 6509-E chassis for sup redundancy. I have found documents that tout how 'cool' and 'awesome' NSF/SSO, and all that is, but haven't found any docs on installing a second sup720 into a chassis that is currently in production and is only running one sup720. In all the years that this chassis has been out, there must me a documented procedure out here to explain this.I have been through the following pages, and have found nothing to this effect.
upgrade experience with the 6509E on what IOS version to use. This is a new install, so I want the most current version that supports SSH and works with dual supervisors.
Here is some information: WS-C5609-E with 983008K/65536K bytes of memory Current version 12.2(18)SXF17b Slot 5 Supervisor 720 (Active) Slot 6 Supervisor 720 (Hot)
Just need a strong base code, no advanced services. Let me know if you any additional information.
Looking at the specs for WS-X6704-10GE, it shows the port buffers at 16M per port. This doesn't seem like very much for a 10G port. Is this upgradable or related to how much RAM is in the blade?
We are experiencing with high CPU input due to ARP input between 20:30 and 22:30 every day At this time we have a lot of backup operations. When I look the netflow report, I can't see anything anormal.
We are changing our backup server's NIC card from 1gig to 10Gig. The backup operation's traffic is high (approx 2Gbps level) but 6509 has to be handle this size of traffic.
We are using two 6509E in VSS mode and our image version is s72033-adventerprisek9_wan-mz.122-33.SXJ.bin
20:00 show ip arp summary -------------- 2588 IP ARP entries, with 166 of them incomplete
I have to upgrade two Cisco Catalyst 6509E from Catos to IOS. I would want to know the requirements hardware or software for upgrading. Which are the recommended images I must download? From cat6000-sup32pfc3k9.8-4-5 to the latest stable version of IOS, is it recomended to pass to another previously version before?
I have viewed the following links,[URL]but, it doesn`t mention anything about that. The image below is the result of the "show version" command of one of our Cisco Catalyst.

we are seeing network latency problems and our cpu on the 6509e is spiking and have a above average % for the past week or so. When we do see these spikes it seems that snmp and apr input is high

we recently upgraded our 3560 switches to the new 12.2-55 ios version but have not upgraded our 6509 because its ios is on 12.2(33)SXJ1. Not sure if this is related or not but it seems that after we upgraded to the later ios that the latency started.over the last 24 hours the spike is several times an hour and at least one a day that it hits the 90 - 100 % mark.is there a way that we can limit what snmp view but would not effect functionality or network?
On my 6509-E, all the modules show this: Region F1: INVALID Region F2: INVALID Currently running ROMMON from S (Gold) region
Is this alright? Is the Gold region like a default region where ROMMON is always installed. And are F1 and F2 just storage partitions that are available to hold backup copies of the ROMMON? From what I read, it sounds like I can copy ROMMON images to F1 and F2, either the same version as the Gold region or different versions. Is that correct? Why would I want to copy different ROMMON versions to F1 and F2?
What is the cause of having a huge number ( 875349) of total output drops on one of my gigabit utp port gi 2/12 which is connected to Cisco 1841 fa0/0 router by mean of cat5e cable.I did change the cable from cat5e to cat 6 and tried to increase hold queue to 4096 and to tweak wrr queue bandwidth
I have two Core 6509E SUP2T configued as VSS and has two 48 ports fiber blades. I have two 3750s, I have two gig on each 3750 port-channle to po1 and connected to both the core, one link to each core.Now, I was asked ot add two more links on each 3750 switch to make it a total of 4 gigs on each 3750s (all 4 gig ports/uplinks will be in used an dtwo links to core one an dtwo links to core 2).when i added two additional links on 3750s and bundled them to po1, I created another port channel on core and bundeled the additional two gigs on each core to accomodate for the two additional links (ports on core switches are not consequtives).
adding these two additional ports makes the 3750 switches flap between managemnet vlan and po1.now, i am not sure if I must have added the two additional links on the core to teh current port-channel or core!? I have created another port-channel on core to accomodate for this currently!?
we have two 6509E, as our core switches. Recently I noticed that on some connections I have a high output queue drop rate.
These 4 x 2 interfaces (gigabit) are connected to our blade encolure, consisting of 4 x WS-CBS3120X-S. The utilization of the links is really quite low, when I see the increase of the drops. (~=60Mbps). All the links are fiber (SFP) and the distance between the core switches and the enclosure is about 15-20m.
I am not aware of any service degradation on the part of the servers. No CRCs, collisions etc, on the interfaces, apart from the drops.
The line card is a WS-X6748-SFP, but other interfaces don't seem to be experiencing any problems.
I have Catalyst 6509 E with redudant SUP720-3B (and MSFC3) running 12.2(18)SXF6 IP Services Lan Only IOS (this IOS requires 512MB DRAM and 64MB of flash) SUP has 512MB DRAM (458720K/65536K) and 512MB sup-bootdisk:, but, there is65536K bytes of Flash internal SIMM (Sector size 512K).
My question is can I put 12.2(33)SXJ3 IP Services Lan Only IOS to this 6500 because this IOS requires 512MB DRAM and 512MB od flash?This is "sh ver" and "dir all-filesystems" of my 6500:

configuring EtherChannel between 3750-X cross-stack and 6509E switch. I use two ports on 3750s, and two ports on 6509. I just need it as a trunk. For some elusive reason one port on 3750 keeps being err-disabled, and one on 6509 notconnected.
I have an issue that I am trying to track down. When I have 2 servers on the same VLAN on my AS pair, all is good because nothing leaves the switch. Where the issue is, is when I have 2 servers on different VLAN's and it requires a hop across the Core router pair. This hop drops the throughput rate by about 20-25% (from 44M to 35-36M)I think I know the issue, but want some input to from other to make sure I am not off-base. I have a pair of 6509E chassis' running Sup720 (VS-S720-10G) with CEF720 (X6748-GE-TX) modules. This is my Access Pair running VSS to look as 1 switch.
These tie into the Core pair of 6500E chassis' running Sup720 (Sup720-3B). This issue I see is that the core has a CEF720 card (6724-SFP), but the AS pair does not connect to the core on that card, they connect on a RJ45 Ethermodule (6148A-GE-TX) card. Would the fact that the AS pair does not connect to the core on the CEF7220 module on the core, cause the traffic to not make use of the CEF features of the Core and make each packet then have to be processed by the core instead of Express Forwarded?
I have one Catalyst 6509E chassis and two SUP720. The bootup sequence on SUP 720 (standby hot) failed . Messages that appear on SUP 720, on the console port indicate o software crash. I don't have a flash card in SUP720.
This is the bootup process:

I am having a LAN with 30 switches and . Is it possible to create seperate dashlet/dash board to moniter only the uplink trunk ports of Lan Excluding acces ports with LMS 4.2?
I have the following scenario: Pair of Cisco 887VA routers acting as Layer 3 for Voice/Data VLANs with a pair of 2960 LAN Base switches acting as Cores and possibly then 2960 LAN Lites hanging off them as access switches. Our Service Provider has provided an example config where the class-maps match based on dscp values for the QOS policy applied to the DSL circuits. We can obviously trust the attached phones but I want to be able to mark data traffic on my core switches based on destination IP/port to allow application definition. My major question is can I have a service policy on my Layer 2 uplinks to the routers where the linked classes setting dscp vlaues are based on class-maps matching on the contents of IP access lists based while at the same time not remarking the EF marked packets from the phones?
