I've noticed that when using the range command to configure multiple interfaces on a 3750 the SSH session oftens hangs. It's seems the more interfaces in the range command the more often it hangs. I have a feeling it also spikes up the CPU. Doesn't seem to be related to a specific version of code.
View 6 RepliesIn my customer having 3750 switch and they have simply assign IP address for vlan and enable telnet in switch and other things are same as default switch.In this switch they have connected 8 cisco layer 2 switches(6 managed and 2 unmanged switch) and approximately 5 servers connected in this switch.In a particular interval,users accessing File server are connected to 3750 switch become hanged for few min.This happen for some particular interval.users accessing this server becomes entirely hanged for few min,then i have configured port monitor cmd and i have installed one wildshark tool to host connected directly to that switch.

IOS on RMAed FWSM is 2.3.4 and cisco VSS supports FWSM IOS 4.0.4 and later.My issue is, I cannot access FWSM (IOS 2.3.4) via session command from cisco 6513 but could successfully consoled it without any problem. I have reloaded it twice and also tried to disable and enable power on it.

why I cannot access FWSM through session command ?Whether this is because of older IOS ? If yes then how to upgrade its IOS ?Is it possible to upgrade IOS via FWSM console ? if yes, Do i need to test on different slot ?

we are facing issue for unstability of EIGRP neighbor with ISP router.Both router are connected via 3750 switch.There is no misconfiguration or physical media issue.I found the SDM template on the middle switch is desktop default, does this will impact ? [code]
View 3 Replies View RelatedI have 100+ 3750's that are running various IOS, some stacked and some not, and all seem to have the same problem.If I attempt to paste a configuration into the terminal session I get booted after about 10 to 15 lines. This happens when using SSH and Telnet. Telnet will go a little further before I'm booted. After I'm booted it sometimes takes a minute before I can log back into the switch. Any issues pasting configs into a 3750 via a VTY session?
View 4 Replies View RelatedThe network is set up like this.
Host -----> 3750 (classic) running IPSERVICES stack ----> 3550 router -----> VPN 3005 Concentrator.
IP routing is disabled on the 3750 (it's acting solely as a switch) IP routing is enabled with an EIGRP process running on the 3550 router that has the network for the 3005 broadcasting.
I can ping the vpn 3005 concentrator from a telnet session in the 3550 but not from the 3750.I can ping between the 3750 and the 3550 vlan management interfaces. Visually speaking it's like this
3750 ------> 3550 [Success!!!!]
3550 ------> VPN 3005 Concentrator [Success!!!!]
3750 ------> 3550 --xxxx--> VPN 3005 Concentrator [Timeout....]
I know this because I tracerout to the 3005 from the 3750 and it resolved the default gateway configured for the 3550 properly but then started timing out.
The 3750 is trunked to the 3550.
3750 is vtp client mode
3550 is vtp server mode
I'm wondering if there's a layer 2 issue involved here as it is a VTP domain and maybe it's not returning properly.
Is there a command to find your optical tx/rx power (dBm) on a 3845? On a 3750 you can do a show int transceiver; looking for a comparable command for ISRs.

View 14 Replies View RelatedWas building a small network in Cisco Packet Tracer and ran in to an issue. I have 4 routers running OSPF, and off one of the routers I have 5 3560 Multilayer switches. The router that the switches hang off of, I have a sub-interface with dot1q encapsulation, set for vlan 10 and an IP Address. 10.14.16.1/24. The switches have interface vlan 10 configures, and have IPs in the same subnet. From that router, I can ping/telnet to all the switches without issue. My problem arises when I try and reach those switches from any other router. OSPF is set to redistribute static and connected subnets.The routing table is populated correctly on all the routers. When I ping and trace the packet, it looks like it makes it all the way to the respective switch, but the packet never makes it back. I've played with the default route on the switches to no avail. Am I trying to implement this incorrectly, or am I just missing something?

I am having issue with a RV082 with firmware:

On setup 1 I have;Using 2 WAN, 1 from fiber 5mbps symetric fixed public IP and other is DSL private dynamic dhcp address 3mbps/900kbps
On setup 2 i have:Using 1 WAN, from fiber 5mbps symetric fixed public ip Both router have exact same firewall configuration, subnet and port forwarding and we have the seccont backup DSL coming in a few day for setup 2.on both setup, the RV082 is the main internet gateway/firewall for a set of server...
Setup 1 work perfectly and been online for 2 week (since install) without issue
Setup 2 worked for 2 day then had to reboot, then work for few days then need reboot, now it look like it need to be rebooted every day. the internet just stop working and a simple reboot does the trick... also, when that happen I can stil remote in server that have port forwarded in the router or connect to router management port, but internet on the server is down... I tried opendns and google dns on both WAN connection and still no luck.I have followed instruction on various support forum;
-more reliable dns server
-lower MTU
-failover vs load balance
-disabling SPI and DoS protection
at this point I'm about to swap both router to see if it not a defective hardware or disconnect DSL WAN on setup 1 to see if its more stable but the whole point of installing this router was for Internet redundancy which so far dosent work as expected.
I encountered an issue while trying to boot Catalys WS-C4948-S switch. I power on the switch and I'm able to see the boot messages thourgh serial console cable.

I tried to use different kinds of IOS images, tried to boot from tftp but with no luck, the issue is the same.
There are no erros on the screen, it just gets stuck when it enters into IOS, so I don't see the IOS prompt.

View 9 Replies View RelatedOne of the companies I work for uses a DIR 655 router. I'm having some trouble using FTP there.Initially the problem was that FTP software would hang or give errors when trying to change directories on the remote server. This problem went away when I switched from passive FTP to Active FTP.Now using Active FTP, the files appear to be uploaded with no problem. However, on closer inspection, the uploaded file has 0 bytes on the remote server.
We are uploading from a Windows 7 machine and uploading to our Web Hosting Company's Windows Server. I've actually written the one piece of software that is showing this problem but it uses a widely known open-source FTP library written in .NET. I've never encountered either of these problems with my software until I encountered the DIR-655.The other FTP software client I've tried is FileZilla. It has the same problem, 0 bytes files when using Active FTP.
One solution I've seen on DSLReports was to disable the Stateful Packet Inspection part of the firewall (known as SPI). This is really not a good solution for two reasons. Number one, I do not have access to the router's firmware/ configuration. Number 2, the company has a DIR-655 because they want the additional security. If we're going to disable SPI it just defeats one of the major purposes of owning the DIR-655.
I had my exisiting Huawei 3G Dongle replaced with a new LTE USB Dongle Huawei E392 from M1 Singapore. The router dectects it and I was able to get on to the Internet. But every after few mins, the connection will just hang and I have to go into the router to re-establish the connection.
