Cisco WAN :: 3750 / Retrieve Tengig Interface Serial Numbers Via CLI?
Jun 13, 2011it's possible to retrieve Tengig interface serial numbers via CLI? We have a couple of them in 3750 switches, and we need them for our inventory.

View 1 RepliesIs there a way to change interface numbers on a 3750 stack but, still retain the config of the physical port?
For instance:
I would like to take the top switch, which has the ports numbered g2/0/1 - 52 and change them to be g1/0/1 - 52. And the bottom switch, which has ports numbered g1/0/1 - 52 and change them to be g2/0/1 - 52. Basically, just swap the interface numbers but, not effect any interface configurations.
I am in the process of implementing 750 Cisco Access Points acros the business. I need to make a note of the serial numbers and Mac addresses for our inventory before I get these configured and sent out to their relavent destinations. The AP's have have arrived in boxes of 10 (75 boxes). The sticker on the box with the barcode is either covered with a postage sticker, ripped, or my scanner will not scan it becaise it is too small. There is a sticker with the serial bundle which is larger and therefore scanable. Is there a way that I can scan this and get the MAC address and serial number.
I know that this is not a technical question but I don't want too spend the next 3 weeks opening 75 boxes and removing each AP individually and recording it.
just ran a discovery on a large network and found 49 wireless controllers (5500, 4400 and 2000 series) and none of them are showing the controller serial number. They are all running 7.0.235.0 and I found no bugs that match this issue.

I undertand I will have to reboot the stack for the change to take affect but here are my questions: How would this change affect the stack running-config ? will the switchport config follow the change ?

I have a 3750 as core switch, adding 2 stacks of 2960S to connect. I want to establish etherchannel between the 3750 and each additonal 2960S stack, do the channel group numbers between the 3750 and the new 2960s have to match? 3750 has two channel-groups(1 and 2) already configured. Need to know, I would create 2 additional channel groups (number 3,4) for each of the etherchannels between the 3 2960S Stacks and 3750? OR channel-group # is local to the device.

I have a remote site that still utilizes a single T1 connection to me. For multiple reasons we had to scrap the old T1 and have a new one put in. The old T1 resided on a T3 as channel 25. The new T1 is a standlone point to point. I removed the old config from my 7301 and programmed my 3725. I cannot figure out what is going on but the interface stays down/down. There is no loopback turned on, either manually or by the carrier. The AL LED stays amber regardless of whether or not I have a cable patched down. The CD LED remains green when I patch a cable down. LP is not light.I am using a straight through Ethernet cable to connect my 3725 to the smart jack. If you look at the show output below you will see DCD and CTS is down. Since the remote end was working and I just had the tech move the patch cable from one smart jack to another I am assuming the problem is on my side or with the carrierI already tried changing the clock sourced between internal and line. I also swapped out the WIC card for another one. I don't usually program T1 connections. [code]

View 6 Replies View RelatedWe have a Cisco 1760 router . We are facing sevier packet drops in the serial interface.
When i swap the router with another router link is working working fine.
Troubleshooting steps taken
1. Swap the serial cable with another working cable : no change in state
2. Reconfigure the encapsulation commands (with PPP and HDLC) : no change in state
3. Try with a decreased MTU packet Ping : no change in state
4. Decreased the Input queue and increased the output queue size using hold-queue in command : Comparatively the packet drop is reducing but still a 10 percent drop is happening.
What would cause an interface to show up/up (looped), but you still can't ping that loop?...It is on a Cisco 7613 with an Enhanced FlexWan (WS-X6582- 2PA), with a Mx Serial PA, 8 ports (73-1580-10) and running IOS ver 12.2(33)SRE2 [code]
View 5 Replies View RelatedI'm having an issue that I can't quite understand. I set up a test lab to get familiar with EIGRP routing. I have a Cisco 3845-MB with 2 VWIC2-2MFT-T1/E1 cards.sh ip int brief shows UP UP status on all serial ports. I gave it an IP address but I'm having trouble pinging the serial interface IP. It's dropping pings to its own S 1/1/0 interface when pinging from console. I have known good T1 crossover cables 1&2 - 4&5.
Here is the "ip int brief" from 3845-MB

Right now it's pinging itself at about 60 -90% success rate... and I can't figure out why it's dropping any packets at all. I have other issues with in the lab as well... but i think this might be my "core" issue.To make matters even more "weird" I've tried two different VWIC2-2MFT-T1/E1 cards and I drop pings with both of them.

I just recently bought a new Cisco 2611 for my home lab and am having trouble getting the serial port to work. I have tried multiple things such as erase startup, switching the cables to rule them out, and even changing IP addresses but none worked. [code]

View 7 Replies View RelatedWhile I managed to connect to each router individually, I decided it was time to connect the routers together via serial; as I don't have any serial cables and need to buy some, what serial cables I need, as well as to ask whether I have the right cards in my router(s) that will allow me to do so.
I bought 3 1841 routers, and all have a 1 port serial WAN Interface Card (WIC 1-T); one router has 2 of these, and one router has a WIC-1B-S/T .. My question is, can I connect the routers with a serial cable via WIC 1-T, or do I need a 2-T
I just finished setting up a bundle of (2) T1's in a multilink bundle and I'm having issues with one of the T1's not wanting to join the bundle.
The router I'm using on the remote office location is a 3620 router running code c3620-i-mz.121-1c.bin
The campus router which is a 7206 is setup the same exact way with multilink 240 and like I've said, serial 0/0 is joined to the bundle just fine, so we are running off one T1 connection.
The serial interface that is not working is: serial 0/1

We currently have Cisco WS-X6708-10GE blade installed in our Cisco 7606-S switch. Each of the ports have a X2-10GB-SR tranciever. When I look at the port with the "sh int tengig xx" command I see the following:

I am planning on deploying a 2960 switch and will need to uplink it to a 4510 switch. There are 2 TenGig Ports available and I was thinking of uplinking one of them to the 1Gb SFP port on the 2960. Would this work?

I have two 3750 switch.switch A(main) and switch B is connected by OFC but i have another wireless link for backup.Now if OFC goes down then i manually connect wireless link with switch B for this reasons i am faceing a lot of problem. I want without any changing of cable if my primary link goes down then my backup link automaticaly goes up and vice versa .
Switch-A port gi1/0/9 and Switch-B port gi1/0/9 is connect by OFC Switch-A port gi1/0/8 and Switch-B port gi1/0/8 is connect by Wireless link (backup) i attach my network diagram kindly find the attachment file.
I'm troubleshooting a 3750 switch stack problem where computers are showing input and CRC errors. I'd like to be able to execute a "show interface" command that will show me only the line showing the switch port and the line showing the input errors, but so far I can't figure out a way of combining those two parameters.
If I do "show interface | include Ethernet[0-9]�" I get all the lines showing the port numbers:
GigabitEthernet1/0/1 is up, line protocol is up (connected)
GigabitEthernet1/0/2 is up, line protocol is up (connected)

My internal network consists of Catalyst 3750 switches segmented into different VLANs. There is a default route on the layer 3 Catalyst switch sending all unknown traffice to the inside Internet of the ASA 5510. However, I'd like to have a separate VLAN for wifi guest access and send all of that traffic through one of the DMZ interfaces on the ASA 5510. I don't think you can have separate default routes based on VLANs on the 3750 switches so my only option is to make the ip address of the DMZ port the default gateway for all hosts on the wifi guest VLAN.
The problem I have is that I have a couple servers behind the inside interface that have services available to the public Internet via a NAT address on the outside interface. I want the guests on the wifi VLAN to have the ability to access the servers on the inside interface using the public address as well, but have not been able to come up with a solution yet.
Here is my config that pertains to this setup:
