What the little green/red light is on the back upper left corner of the switch is? It inside a little mesh and I belive it says vt_fail next to it.
Had water get on our switch over the weekend and this guy goes red when I fire off on demand diagnostic, but not relevant errors in any of the logs. Haven't gotten to the point where I am putting data back on the switch yet.
I have (2) Sup 32 configured in a 6509 chassis. I have 1 power supply plugged into the wall and 1 power supply that is not plugged into anything but it is in the chassis and has green light to show that it has been recognized.
My problem is the "system light" on both sup32 remains amber and does not turn green. I have done show modules and sh diagnostics and sh power and everything checks out OK. Also there is an amber light on "active" on the 2nd Sup32 which I am assuming means that it is in standby mode so that would be correct.
Q: My question is could it be the power supply that is not plugged into anything causing the "system light" to stay amber and not turn green?
Q: Will this amber system light on the Sup32 stop the 6509 from running as normal?
I have a Cisco 8510msr that is connected back to back with a 7206vxr across a 155Meg connection.I receive lots of Output drops on the 7206vxr interface facing the atm switch. When I do the following command:-

I have a Linksys E2500 and recently the power led light on the back of the router started blinking. The router itself seems to be working fine. I can access the router and the router seems to be assigning the IP addresses fine. I did look up the issue on the knowledge base and tried all the solutions but the light is still blinking. Not sure what to do anymore.

I am trying to connect a cisco catalyst 3750g-48ts with our exsiting 3com corebuilder 9000 using the SFP ports, I have established a link and the interface is up.
The issue is that no data is passing through between the two, everything looks like it's up and enabled, spanning tree has detected the uplink port and has automatically set it to forward, both devices suggest the link is in place and the lights are on .
I have a bunch of 3750x switches that each have a 10 gig routed link back to a central 4507 (loopback = 172.30.255.255).We carved up a /24 (of course, the /24 doesn't really exist except in our address tracking spreadsheet) into a bunch of /30's for routed WAN links and /32's for loopback addresses.We started on the low end for /30 subnets (ie 172.30.255.0/30, 172.30.255.4/30, etc.).We started at the high end for the /32 loopbacks (ie 172.30.255.255/32, 172.30.255.254/32, etc.)
Well, when I try pinging 172.30.255.255 from the access layer 3750x switches, the 3750x seems to be treating it as a broadcast ping where it lists each member that responds instead of the regular !!!!! response (this makes think something is odd with the 3750x). Of course, only one member responds (the core). But even the core seems to respond with the other end of the /30 instead of the actual /32 loopback (which makes me think something is odd in the core). I could have sworn that I've setup similar topologies without problems (ie, using 10.0.0.0/32, 10.255.255.255/32, etc as loopbacks) and as long as the mask is a /32, it should work.Also, I can ping/ssh to that loopback if my laptop is on a directly connected subnet. But I can't do it from any of the 3750x switches (which are also directly connected).I've double checked for overlapping subnets, but nope. I don't see any. Routing looks fine. The actual /32 is being propagated everywhere properly.
I have a network that has a pair of 6500 switches on either end, running HSRP. In between each 6500 are two to three ruggedcom switches. They are connected to each other and the 6500's by trunk ports in a straight line. The 6500's see each other as CDP neighbors, and the 6500's can see the rugged- com as LLDP neighbors (ruggedcom only supports LLDP).
The issue is that randomly devices on the ruggedcoms will drop offline and then come back. The problem is that the devices that drop offline are all in the same VLAN, so it appears like a virus - i.e. one device drops off, then multiple. Eventually the HSRP starts flapping between the two 6500s and this causes havoc on the network.I'm almost to the point of taking a laptop and plugging it into one of the ruggedcom's to see traffic, but the issue is that the ruggedcoms are outside in cabinets that laptops shouldnt be exposed to.
The following error was seen on the switch and the Diagnostic Test Loop back failed following a new WS-6748-SFP module installation.Fabric in slot 5 detected excessive flow-control on channel 3 (Module 4, fabric connection 1)
Tried Hard reset of the module and still the error persist.
We recently extended our access layer using a pair of 5ks with extenders. We have a pair of 6509s at our core and they handle the intra-VLAN routing with SVIs. I recently noticed that access hosts connected to the extenders cannot pass traffic between each other if they are in different VLANs. The strange thing is these same hosts can ping devices in other VLANs as long as the other devices are not connected to the 5k environment.
For example, consider the following hosts. Each host has their gateway set to the appropriate SVI on our core.
HostA - VLAN100 - connected to 5k extender
HostB - VLAN200 - connected to 5k extender
HostC - VLAN100 - connected to 2960 off our core
HostD - VLAN200 - connected to 2960 off our core
Each host can ping each other with the exception of HostA and HostB. As for specifics, we use HSRP (no VSS) between our cores.
When I ping between hostA and hostB, I see the egress packets on either 5k1 or 5k2. I then see ingress AND egress on Core1. There are no ingress packets on 5k1 or 5k2.The egress packets from Core1 show the correct destination MAC address of the target host. The mac address table shows the mac address on po31.
I just completed installation of a stacked pair of 3850s in my datacenter. While I was installing them, I noticed that the lights on ports 1-8 on one of the switches were on solid even though there were no cables connected to that switch. I don't see anything in the logs or anywhere else in the CLI that indicate a problem, however the lights remain on. This only happens on switch 1, not switch 2. Once I plugged the cable into port 1, it flashes normally with activity, but 2-8 remain on solid even though nothing is connected to them.
Before I put the switches in place, I had configured them at my desk with the console connection, and those lights were not lit up.
The indicators on the front of both switches are set in STAT mode. I thought initially I had hit the button and flipped it to a different mode, but that is not the case.
I'm having with VSS Failover. Currently I have two 6504's setup for VSS with one connection to the sup engine (10Gig__Connection) and the other connection on the Module 3 10Gig Blade and the same setup on the other 6504.My question is: If the active 6504 has a power outage or the link on the sup engine goes down, and the standby 6504 becomes active, what happens when the Failed 6504 comes back online with a higher priority and preempt set? What happens with the 6504 that took over as Active and now eeds to go back to Standby, what's required?
What I'm seeing is once the Standby took over and became Active in order for him to go back to Standby mode it's asking for a reload to take place is this NORMAL?

View 9 Replies View RelatedI have a lab setup to take my CCNA and CCNP and I'm having issues trying to get WAN connectivity back to a switch at the end of my network. My lab environment consists of 1 - 2950 switch, 1 - 2620 and 1 - 2621XM. I have 1 Ethernet connection from each router to the switch and 1 serial connection from the 2620 to the 2621XM. I have the serial interfaces in a shutdown state right now so there is no loop since I do not have Spanning tree setup on the ports on the switch yet.
Right now using the fast ethernet ports on the routers and I have no issues its when I shut down those Ethernet ports and try using the serial interfaces when I start having issues. So my network layout is Ethernet from switch port f0/4 to port f0/0 on 2620 and serial from s0/1 on the 2620 to s0/2 on the 2621XM. My 2621XM f0/1 is whats connected to the WAN and I have no issues getting to the WAN from my 2621Xm or my 2620 but when I try pinging any website or even my WAN default gateway from my switch I get nothing!
Ive also noticed that when I do a IP NAT translation (after accessing the WAN from my 2620) on my 2621XM the source IP is of my serial connection not the ip of my 2620 router? I have my default gateway on the 2620 as the the IP of my serial interface on the 2621XM and vice versa because my LAN network is 172.16.1.0 and my WAN is 172.16.9.0. I have a /31 setup between my serial connections 172.16.11.0 (s0/1) is on the 2620 and 172.16.11.1(s0/2) is on the 2621XM. I used the SDM (ver 2.5) to setup NAT to have f0/1 with Nat outside and s0/2 as Nat inside. Encapsulation is HDLC between the serial links. Ive attached the running configs of the switch and routers.
we've had an issue with our network, we have 2 6509 connected with redundancy, which are connected with 2 x 4900 Switches, from which are connected to a ESX Chassis for visualization, the thing is that the ESX stopped working, and the 4900 switches, and the main core were suffering from overload, they hang on it very well, in order to stop the overload, one of the links to the ESX Chassis were disconnected from one of the 4900 switches. The CPU usage from the 4900 and the core(6509) went down below 40%, and then they started to migrate the virtual servers from the chassis to another 2 chassis that were added right after. They were actually working well, but suddenly the 6509 changed to the other supervisor after everything was OK. We were wondering what could have been the cause of this, maybe the virtual servers migrations, maybe the overload from the ESX ? We also had a few question, is there any need to reload the cores every few months as a planned task ? Because the cores have been up for more than 1 year. And also is there any kind of of tool to monitor the CPU status, or the status overall from the cores or the switches ?

Maybe I can explain better:
I've got a Cisco 6509 with 4 configured vlan interfaces
Int Vlan 10 10.10.1.0/24
Int Vlan 20 10.10.2.0/24
Int Vlan 30 10.10.3.0/24
Int Vlan 40 10.10.4.0/24
Vlan "10" is the phone voip Vlan and it must not talk with the others Vlan. The others Vlan can comunicate normally except with Vlan "10".
Pratically Vlan "10" needs to be isolated from the others.
This equirement comes becouse Vlan 10 is wireless and has the WEP key encryption (very weak protocol). Some Phone couldn't support the WPA2 key and I need to avoid an unauthorized external client, cracking the WEP key and connecting to this WiFi, could have free access to the others Vlan.
I have a problem on my catalyst 6509 on which I would like to do the following things :
I have some Vlans in which multicast is enabled.
In tose Vlan theres is a router which is default router for equipements.
I had enabled multicast routing because some Vlan needs to exchange multicast informations, but I wolud like to make difference between Multicast traffic. For example I have 5 vlans:
Vlan 1 and 2 need to exchange Multicast informations but the don't need multicast information from Vlan 3 and 4
Vlan 3 and 5 need to exchange Multicast informations but the don't need multicast information from Vlan 1 and 2
Vlan 5 is independant Vlan but doesn't need to have multicast information from all others vlan.
Last problem, equipement on differents vlan can use the same Mulkticast group address. In this case, Multicast routing is not working between Vlan 1 to Vlan 2 and Vlan 3 to Vlan 4.
I need to setup my 6509 with PBR going to two different Firewalls. The 6509 has vlans and multiple serial interfaces. What/where do I install the policy-maps? I want to direct one of the vlans to one firewall and the other vlans and wan subnets to the other firewall.
