Cisco Switching/Routing :: 4900M WS-X4908-10G-RJ45 Port Startup Delay
Mar 4, 2013
We have recently purchased 2 x 4900M switches with the following configuration:
2 x X2-10GB-SR installed in port te1/1, 1/2 (optical)
1 x 20 x 1GB RJ45 installed in the top left of chasis ge2/1 - 2/20
1 x WS-X4908-10G-RJ45 8 port 1/2 card in the top right of chassis te3/1 - 3/8
We have te1/1 connecting the 2 switches, and various vlan's and connections on the 1GB RJ45's with no problems.
However, we have a number of 10Gbps BaseT connections te3/1 - te3/5 which are causing us issues. On a reload of the switch or removal / re-install of the cable it can take anywhere up to an hour for the port to become active again. So when we reload the switch, we may get a connection come up after say 3 mins, but the port next to it may not come up for 15-60 min. The cabling is all the same (CAT6 and has been tested/verified) and all connections go to Broadcom 10Gb cards in Dell 820 servers running vmware. We have the following set on the ports:
switchport mode access
spanning-tree portfast
No speed or duplex can be set on these ports - these options are not available in the config.
Once a link is finally established, it will hold the link solid with no problems, but this is a problem for us, we can't have a reboot take an undetermined amount of time for the link to come back.
I have Cisco 800 series (888w) with BRI-ISDN port. Is there any way to change the usage of ISDN port to normal RJ45 port?I want to use this SOHO router to sharing connection.
One of branch locations has a Cisco 1941 Router . The port details are as follows
-Gi0/0 - ISP line -Gi0/1 - Inside Network ( To a 2960 Switch)
Now they have procurred another line from ISP through which MPLS based VPN to the Main location is configured. What are the options I have , to terminate it on the Router ? As all the On board LAN ports are filled I guess I wont be able to do anything with the current setup .Are Switching modules available ? What is the Embedded-Service-Engine0/0 port that I see on #sh ip int b output ?
I am just going to deploy some new 4900Ms for a customer. Want to know if configuring management for 4900 (everything like NTP, AAA, SNMP , DNS ) is doable through management interface in management VRF and there are no caveats to be aware of.
I have an issue with couple of Cisco 4900M switches. We just got them and tried to use the TwinGig Converter on the 4 ports 10G module.
The problem is that the switches sees the new module in slot 2 and when we are inserting the TwinGig Converters we are getting the error message and when we are trying to type the command this command it does not work."hw-module module <slot> port-group <group> select gigabitethernet",When we go to config T, the only thing we can type is "hw-module module <slot> and if we do a ? the only thing is available is logging and power and we can't type
Port-Group or anything else. Is this a hidden command or we have to something else?
on a Cisco 4900M running IOS Software, Catalyst 4500 L3 Switch Software (cat4500e-ENTSERVICESK9-M), Version 15.0(2)SG1, RELEASE SOFTWARE (fc4) I'm getting a lot of packets on CPU Q "L3 Glean, 6".What is that queue and what could be the root cause?
I have a client whom has a 4900M switch as their SAN switch. They are getting ready to upgrade their SAN to use 10G.I had quoted them a price for an X2 module, but I am unclear based on pictures I have seen of the part number
X2-10GB-SR
whether or not the X2 module plugs into the X2 slot on the switch, AND then also has to have a transceiver put in it to receive the SC ends of the Fiber jumper, or whether the SC ends of the fiber jumper plug into the X2 module directly.
They seems to be coming on regular basis, repeating every minute. I've tried Google and the most relevant info I can find is this {URL}. But it says "Upgrade software to IOS version 12.2(52)SG or later OR 12.2(50)SG4 or later. ". I'm already running 12.2(54), so why does this 3 line repeatedly show up in the log every minute.
i am facing time daely issues on cisco 2960 s series switch while booting .It is taking time for electing masrer and sleeve for stacking.can i disable the election process for stcking while booting.
First time user of cisco hardware and we just purchased the 4900m catalyst switch. My question is very general. I am simply hoping to network 3 servers together and I do not wish to do any fancy or advanced configuration. Can I simply use the web management interface for network administration and setup? I just downloaded the Catalyst 4500 Series Switch Cisco IOS software configuration guide and they talk about Cisco View network management system, is this my answer or is this what most people use for basic configuration and administration?
I currently have IOS image cat4500e-entservices-mz.122-53.SG5.bin. According to my research it appears SPAN is supported on this OS. However, after looking at procedure notes using websites like here:
[url]... I cannot find and obviously not figure out how to use the SPAN command. My main objective is to simply setup a port mirror on one of my TenGigabitEthnet interfaces and from what I read SPAN is the best way to setup a tap interface on a cisco switch.

We have to cisco WS-C4900M with Cisco IOS Software, Catalyst 4500 L3 Switch Software (cat4500e-IPBASE-M), Version 12.2(53)SG5, RELEASE SOFTWARE (fc1).We have four gigabit link connected between those two switches.We have create a LACP port channel with those four ports on both switches. Ether-channel is up and running and defined with a load-balancing method of src-dst-ip.But when we test the load-balancing, it's not using the src-dst-ip rule with the XOR: [code]
I have 4900M with X2-10G-LX4I need to have a link from it to 3560X GLC-SX-MM using MM Fiber Patch Cord.any configuration required in 4900M to change the speed of X2-10GB-LX4 to 1GB ?
My current version IOS is cat4500e-ipbase-mz.122-53.SG5.bin. I just got a new version cat4500e-entservicesk9-mz.122-53.SG5.bin.I put the new version in bootflash: directory and tried various methods of starting the IOS up to run the new version but it always started in the original ipbase version. My start-config shows:
boot-start-marker boot system flash bootflash:cat4500e-entservices9l-mz.122-53.SG5.bin boot-end-marker
and I even deleted the ipbase version in the bootflash: directoy so then my switch would not even boot up at all and hung in rommon. In rommon I tried
boot bootflash:cat4500e-entservicesk9-mz.122-53.SG5.bin and the result I got back was File has bad file magic number: 0x0
So I had to point the switch to my tftp server and boot back into a back up copy of ipbase. how I can get my new IOS version to work? I understand I might have to download it again but I just got it so I am skeptical it is a bad file. [URL] as a procedure guide and I do notice some of those commands/steps do not work on my 4900m switch.
I have been trying to get the http server enabled so I can access Cisco Network Assistant. I have my interfaces configured but for some reason the server in not running, port 80 is still closed. [code]
I' ve three 4900M switches equipped with the WS-X4920-GB-RJ45 module and the WS-X4908-10GE module. Now I'm started to setup these switches in our lab environment for the first time. They behave a little bit strange in comparison with the C3750 series which I used before and which I will replace by these powerful machines.
I tried to setup these switches to be managed through the management port. I configured IP address, default route in the management vrf, set the source-interface for tftp,ssh,ftp and tacacs to use the management port. Ping using the manangement port was successful. After finishing theses steps I configured the TACACS and AAA settings accordingly the informations I found on CCO. I tested the settings with "test aaa group authentication" command- without success. On my Cisco ACS no request was received and the switch told me he could't reach the tacacs server. Other switches in the same IP subnet are working without failure, so firewall or server should not be the problem.
Can I use GLC-LH-SM, GLC-LH-SMD and SFP-GE-L with Twingig converter module? When I used Cisco configuration tool, the only option is GLC-LH-SMD for 1000BASE-LX.
I was wondering if a interface numbering scheme is available for the 4900M. Configuration includes 1 x 8Port 10G and 1 x 20Port 1G modules. would like to understand How the slots are addressedInterface AddressingTwinGig interface addressing
know if Private Vlans are supported on the Cisco 4900m switch when set in VTP version 3 and VTP disabled?Most documents just specify VTY transparent mode without mentioning the version, trying not to assume since this is production.
Got a question for 4900m with TwinGigi Converter. I bought couple TwinGigi Convert thinking to use it on fix module ports (8 * 10G ports on 4900m ten1/1 to 1/8). I follow TwinGigi configuration guide [URL]however, I am getting Invalid commands on hw-module:
Switch(config)#hw-module module 1 ? logging Logging Switch(config)#hw-module module 2 ? logging Logging power Enable/disable power to module in specified slot
[code]...

I am slowly working my way though the setup and configuration of our new 4900m switch. The switch will have a pretty basic operational configuration. We are simply going to network 3 servers together through the swtich. Anyhow, I have been fallowing the guide at this site: [URL]
Basically the switch is brand new and I just setup things such as the clock, the banner, and the hostname. Anyhow, at various points in the guide such as the configuration of the telnet password and especially the interface gigabitethernet I get the "invalid input detected at '^' marker". I also did a show interfaces and noticed there was not any gigabitethernet interfaces but there was a
"FastEthernet1 is down, line protocol is down Hardware is Fast Ethernet for out of band management, address i"
Anyhow, my thinking is continuing on with the guide and at least try to setup the interface for the management port so I can then use the cisco network assistant gui to then configure the rest of the switch.
I had setup a lan infrastructure with 5 3750 stack swithes. In these 3 of them are in one stack which is acting as access switch, 2 of them in another stack which is as core switch where all the SVI is configured. Now, when i tried to ping from our edge pc which is connected in access switch to default gaeway, which is configured in core switch, the ICMP is getting delayed . But when try to ping from the same edge pc to another user PC, it is getting less tahn 1 millisecond icmp replies.
why icmp is delaying to default gateway , but working with another edge to edge pcs without any delays?
i am facing a problem when the client vlan is commmunicating with the default gateway on the core 3750-x.
ios in 3750-x core is 3750e-universalk9-mz.150-2.SE.bin. But, client to client communication is happening without any dealy and icmp is less than 1 ms always.
When try to ping default gateway of client vlan, it is getting delayed (variable icmp delays). Is this an ios bug?
I'm setting up a new 4900m running cat4500e-ipbase-mz.122-53.SG5.bin. I'm attempting to create Port-Channels as a Trunk for uplink to a 4503 running cat4500-ipbase-mz.122-37.SG1.bin.When I attempt the command "switchport trunk encapsulation dot1q" it errors out.
