I have a Cisco catalyst switch 3750G has all LED lights staying amber still without blinking, I cannot console into it and it can’t boot past the POST.
THE ISSUE HAPPENED ON THE NETWORK AND IT WAS ISOLATED FROM THE NETWORK, SO NOW I AM TRYING TO RESOLVE IT OUTSIDE THE NETWORK
I am replacing an old Catalyst 3550 (that has 2 Gig ports) with a 3750 (that has 4)- I used the exact same configuration in the new switch. When I plugged in the new 3750, the trunk ports started blinking from green to amber. I dont know why this is occuring- it SEEMS to be fine, but we havent thrown a whole bunch of traffic over it.

cisco WS-C3750G-48PS (PowerPC405) processor (revision F0) with 0K/12280K bytes of memory. This would equate to around 11MB memory which does not seem right... Is it a known IOS bug?
I have a PS3 connected to a Gig port on my 3560. When I boot-up the PS3 I have to wait around 30 seconds for it to get DHCP.
I noticed the orange LED would stay on and go green after 30 seconds. I assumed I would have an error-state but I do not, the port show connected with no errors even though it's orange. I have no connectivity from the ps3 until the light goes green and then all is well. The port is access and I have manually configured duplex and speed.

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?
In our company 3nos Cisco 3750 (WS-C3750-48P) access switch in stake mode. All port are assigned with voice and data Vlan also Avaya IP connected with this switches. From last few days tow port 2/0/7 and 2/0/8 is showing amber and status is showing err-disable. At Avaya end it is showing a message “ETHERNET WAITING” in phone dispaly. I try to connect laptop directly with these ports but it is showing "Cross Connectivity". [code]
View 4 Replies View RelatedI have a brand new 3650x switch that I was configuring via console and left it on overnight; this was friday night ( I forgot to keep the air conditioner on). When I returned Sunday afternoon and checked the switch I realized that the SYS and STAT lights on the front were not on, however the Leds on the PS module were still on. I powered it down and turn it on again but still there are no lights on the front. The PS OK and AC OK leds on the PS module are on but I noticed the leds on the two fan modules are not green or even amber; they are off.When I first turned on the switch I remembered distinctly that there were loud noice and if all fans were in overdrive mode for a few seconds then the went to normal. I'm not gettgin this loud noise phenomenom.

The supervisor has all it LED in orange state, there was no blinking of the lights at power on they went straight to orange. Tried removing all cards, having only supervisor card in, etc but always the orange lights.
View 2 Replies View RelatedI got Two Distribution Switches of Cisco 3750G. Each Distribution have two 3750G switches stacked. I also have one Cisco 3750V2 Access Switch connected to both Distribution. When I am checking for redundancy, I can only get redundancy test pass for one link not atall for other. If I have a link up with Distribution 1 only then its fine; but disappointment with Distribution 2 link. I can see that the switch priorities of Dist 2 is not correct ie. Master's priority is 10 and Member's is 15.
My question is that due to misconfigured priorities on Distribution 2 stack switches I am failing with redundancy if ONLY Dist 2 is up and Dist 1 is down.
I have a switch connect to 2 backbone(BB).
Now i saw the lights when connect to BB1 is not light but i do not know which command will show the root cause or troubleshooting.
I want to know its caused by hardware, physical port or whatever. Any on can sharing the experiences how to show and troubleshooting this issue?
I also checked the connection and port 1g is fine. Show tech-support is alread here.
We recently installed 15 of these switches, and we're having a few odd, random network issues. But before I enumerate those issues, I have a simple question: are the connection lights on these switches *supposed* to blink rapidly? Or are they supposed to blink *normally*?On all other switches I've ever seen / worked on / worked around, when a cable is plugged into a port, the connection lights blink upon network activity. sometimes they blink a little faster when there's lots of activity, but mostly it's an almost lazy, random kind of blinking. When you look at a switch and every light on every port that's connected is blinking very rapidly, your first instinct is "No *wonder* nothing works around here!" and you find the port that's chattering and unplug it...all the blinkies go back to normal.Well, on the 15 switches we've installed, every light that's on blinks rapidly, as if there's an uncontrolled storm going on. Is that the "new norm"? Did I miss the memo, and there is nothing to be worried about here? Or are the rapidly blinking lights telling me there is, indeed, a problem?

could this problem be a version incompatibillity between the switches?
I've one Cisco 3750G-12S with ip routing enable, the swtich is with IP Service firmware, with PRR support.Currently set my default static route 0.0.0.0 0.0.0.0 10.1.18.71 to my Firewall A Currently all of the VLAN for will be routed to 10.1.18.71
I've created a new VLAN 2 for my 10.1.2.0/24 network with the VLAN interface 2 ip address 10.1.2.10, my intention is to route 10.1.2.0/24 traffic to my 10.1.2.1 by creating the access list and route-map.
I've configure my test pc with a static ip and my gateway pointing to 10.1.2.10 (VLAN 2 gateway) , i'm not able to route to 10.1.2.1.
I have a 3750-48P when plugged in has fans that spin up, but no lights on the front of the chassis. Does this mean the power supply is bad? If its bad, why do the fans power up? Also, i am not receiving any data through the console.

View 1 Replies View RelatedI've got a requirement to do Inter-VRF routing (need MP-BGP) using a private AS Number on a stack of 7 x 3750G's, my question ultimately is the performance overhead of doing such a change.
The stack will have no more than 300-400 routes even with the duplicates invoked from doing VRF leaking so I can't see much of an issue myself, we already have 2 VRF's and OSPF running in each VRF just don't have MP-BGP to do the VRF leaking.
Ultimately there will be about 4-5 VRF's (I know there's a Software limit of 26 VRF's on a 3750G).
I am trying to stack the following -
3750G 12S - 12.2.53(SE2 IP Services) Running EIGRP & OSPF
with
3x 3750X 48P-S - 12.2.53(SE2 IP Base License)
Doing some research, the IP Base does EIGRP on the 3750X, does it do OSPF?
If not I will have to get licence for the 3750X?

View 2 Replies View RelatedI have just received a new Cisco 3750G Switch from my parent company. When attempting to install the switch, I discovered that it will not boot to CLI, only to the bootloader. After using the command boot, the switch attempts to boot the most current IOS version, but fails, stating "error loading XXXXXXXXXX.bin".
Obviously, I just need to get a functional version of the IOS onto the switch to boot, but the problem is exactly how can I do that? All (or most) the commands with which I am familiar are unavailable in the bootloader, so all methods known to me fail. Is there a simple way (maybe using the copy command?) to put the .tar or .bin file onto the flash?
I am trying to create an ACL that walls off a VLAN and only allows it to the internet. This is on a 3750G, currently the 3750G I am attempting this on is in a stack. I have another 3750G that is a standalone.
The first way I attempted this was to create two access-lists: access-list 101 permit tcp 10.249.1.0 0.0.0.255 any eq 80 access-list 102 permit tcp any 10.249.1.0 0.0.0.255 established
Let's call the 10.249.1.0 VLAN 2. I applied this to the VLAN2 interface, 101 out, 102 in. It didn't work. If I place a deny statement with nothing else, that works.
The second attempt was this: access-list 101 deny ip 10.249.1.0 0.0.0.255 any access-list 101 permit ip any any
I applied this to a VLAN I wanted to block VLAN2's traffic from reaching, let's call that one VLAN 3.
This lets all traffic from any VLAN (including the one I'm trying to block). If I remove the "permit ip any any", then all VLANs are denied. Which I understand is correct due to the implied deny all. What I don't understand is why it isn't applying the ACL to the specific VLAN.
I have a 3750G that used to be a Stack Master of a stack comprised of 2 identical switches. Since then, we have removed the stack from production, and I factory defaulted the stack MEMBER and that went fine. I just held the "Mode" button on the front until the lights all lit up and then issued the reload command and the switch came back with no configuration OTHER than the vlan database I issued the "del vlan.dat" command to no avail. I just manually removed all the vlans.
The stack MASTER on the other hand will NOT go back to factory defaults, and will also NOT erase the vlan database. Everything I try will NOT work. I've tried the following
1) Hold mode button & issue a reload after the lights start flashing
2) issue "Write Erase" then issue "reload"
3) issue "Write Erase", then issue "Write", then issue "reload"
4) issue "erase start" then issue "reload" (just in case the "write erase" command is being depriciated or something weird)
5) issue "erase start" then issue "copy run start" then issue "reload"
Is there a special way to reset a StackMaster back to factory defaults?
I have one 3750X with C3KX-NM-10GT, I need to interconnect using stackwise to 3750G-24TS. The 3750X needs IOS 15.0(1) to use C3KX-NM-10GT, and the latest IOS for 3750G-24TS is 12.2.55. How can I interconnect them using diferent IOS?
View 2 Replies View RelatedI have a 3750G switch that can't detect another switch or be detected through its stack ports. I tried the recommended test; looping a cable between the ports and rebooting. I get the following message as the switch boots: SM: Detected stack cables at PORT1 PORT2. However, if I connnect another switch, it won't detect it and can't form a stack.
