Cisco WAN :: 2921 Router With Etherswitch Module Baud Rate Unsetting
Feb 14, 2013
I have a 2921 router with 1 etherswitch module installed. I haven't done it before and was trying to change the baud rate to 115200 for installing an IOS on the etherswitch module which had been deleted. I ended up "unsetting" the baud rate on the etherswitch and rebooted. Now, when I try to session into the etherswitch, its opens the connection but I can no longer see any text on the screen. Im using Teraterm. I've tried different baud rate settings for my serial port in TeraTerm but still cant see any text on the screen. I dont know of any commands from the router prompt. Any suggestions to fix this? If can start seeing the text, then I can probably configure and set up the etherswitch module.

configuring up a 2921 router for remote site which is fitted with 24 port Etherswitch module.As part of this setup I have defined 3 vlans on the router, but when I go onto etherswitch and for example set switchport access to access vlan 3 it is not aware of this vlan.Do I have to set up trunk inbetween Router and its etherswitch?Wish I had ordered seperate switch as it would have been easier or am I missing something.sho vlan-switch shows my vlans but on swicth sho vlan brief does not.

I've configured all my devices in the lab to use 115200 baud rate, so I can speed things up a little at the console. For whatever reason, I can't get my 3550 to save the 115500 baud rate. I power on the switch, hold the mode button, at the switch: prompt I type 'set BAUD 115200' followed by a reset. I power the cycle the switch once more, yet it still holds at 9600. I did the same process on my 3560's and it worked like a charm.

Having trouble resetting the baud rate to 9600 on a 3750-E. Basically the device cannot be set to anything other than 115200 baud rate. I have changed this via startup-config (which lost connection) reconnected and saved config but after reload was back to 115200. Tried via bootloader to 'set 9600' but the termial program paused for a bit then the switch prompt returned. Tried the same to 'unset baud' but the same thing as above happened. I have erased and reloaded flash etc

We just received a new C2911 G2 ISR and have been trying to configure the EtherSwitch SM-ES2-24-P module on it. Through the router console, I tried assigning an IP address to the router Gi1/1 interface which I assume is the link to the Etherswitch module but all I'm getting is "IP addresses may not be configured on L2 links" - as per the docs, I should be able to assign an IP address on that "logical" interface link. Any other way for me to configure the ports on that switch module?

it seems that i made a mistake when typing the BAUD rate of a 2960-Switch in rommon.I can't start the switch now, because there is no image on it (because I deleted it before) and the baud-rate has wrong settings. When connecting via console cable i can't see anything (except some strange hieroglyphics) when starting. I tried all the speeds in teraterm... without success.what can i do, to recover the switch back?

Using ES2 enhanced etherswitch modules? Could not find out whether it functions identically as NM-16ESW or not. I do understand that ES3 module act like a separate device connected to the router chassis via internal interface and has its own configuration file and processor resources similar to older NME-16ES modules. What about ES2 card (e.g. SM-ES2-24)? Does it work as separate L2 switch connected to the router chassis via trunked internal interface or integrates to the router like the older NME-16ESW module did? Is it possible to turn its ports into the routed mode (no switchport) and use them for L3 forwarding with routing protocols such as OSPF?

I seem to have managed to set a 2960 to 230400 baud in the boot loader. Is there anyway to reset the variables in the boot loader? Maybe a set of pins to short? I can't access the console port reguardless of what I set the rate too. I've tried both the USB console cable and a USB to serial. Is there anything I can do short of an RMA?

I will like to set auto baud for the SG500. By default its 115200bps.
I had tried the following methods:
1) switch xxxxx (config)# line console
switch xxxxx (config-line)# autobaud
--------------------> my terminal hangs and print out rubbish
2) Using http Administrator ->Console setting ( i cannot find the link with console setting)

I had to format flash and recover. I did the quicker way by using set BAUD 115200...once the .bin was across I forgot to set the baud back to 9600. I have followed instructions: go back to switch: set BAUD 9600 then reset. also tried the unset command. problem is it always comes back up with a BAUD of 115200. CWill I have to label 1 switch as 115200?

I need a router to connect to our ISP by BGP and in a future to a second ISP. Our ISP is going to provide us about 300.000 route entries by BGP. So router 2921 would be enough??? or should i go to a higher model?We are going to have 100Mbps with this ISP and probably in 3 months we'll have to double it. Also we'll need IPv6 support.I saw router performance [URL]f and it's has 480.000 PPS and 245 Mbps but for 64 bytes lenght packages. If the packets are bigger the throughput should be best I suppose... 1500 bytes about 5,5 Gbps. In the case you consider the model is sufficient, the flash or RAM should be increased?

I apologize in advance if this is a novice inquiry, but our company just switched from Point-to-Point T1's to Metro Ethernet.
On one point-to-point, from our main office to one of our high profile locations, we had two bonded T1's. Now this site has a 3 Mbps Metro-E link, but it's being over-saturated. I don't know what type of QOS implementation our T1 provider had, but it prevented flooding. Now, I'm getting horrendous latency as the office peak hours approach since there is no QOS on the mesh by our Metro-E providers.
Ultimately, my question is: what's the best way to set a Fast Ethernet port on a Cisco 1800 series router to limit all bandwidth to 3 Mbps? At the moment, I don't have a preference in which traffic takes priority. I tried the rate-limit command, along with a speed calculator I found online, but that slowed the network down immensely.

I am installing a security license on Cisco 2911 Router for the first time. It already has a temporary license installed on it which is expiring soon. Cisco has already mailed me the procedure for installation. I want to know if i need to uninstall the previous license before installing the new one.

We recently acquire a cisco 2921/K9 router to interface 2 networks
Network 1 : 169.254.XXX.XXX/16 on GigabitEthernet0/0 interface
Network 2 : 192.168.1.XXX/24 on GigabitEthernet0/1 interface
On the network 1 side there is a multicast source (169.254.200.200 destination : 225.0.0.1) on the network 2 side there is 1 receiver which is not multicast capable(old) but i want it to receive the multicast stream for the moment we configure the ip multicast-routing and each interface each interface with ip pim sparse-dense-mode then configure the GigabitEthernet0/1 in order to join the multicast group (using ip igmp static-group 225.0.0.1) and wireshark confirm that the multicast stream on the network 2 side from 169.254.200.200 -> 225.0.0.1 of course the receiver don't the stream, but if i force a "multicast to unicast" process inside the router it shall be ok.. after many hour of internet browsing i found 2 solution :
- NAT, [URL]
- multicast service reflection (Cisco documentation)
The NAT example don't work ,what is the best way to do this task.

I am getting the following logs:
*** External Redundant Power Supply is present, but type is unknown or not supported.***
%ENVMON-1-POWER_WARNING: : RPS Online Insertion and Removal is not supported.
Do we required any configuration to be done on Router end.

I just got a brand new Cisco 2951 router that has built-in 3 gigabit interfaces cards. We want to add additonal 2 GE EHWIC-1GE-SFP-CU card to it. When it booted up and type show inventory, it did not detect the presence of the card. There was light on at the back of it. I have checked the compatibility on Cisco. The card is compatible with this router. Do we have to install the card with special instructions in order for the router to see it?

I have a home network running on a Linksys WAG320n and i have attached to it a WD MyBookLive (w Gigabit Ethernet). I am connected on the network via my Dell with a Intel(R) WiFi Link 5300 AGN. I am not able though to connect on N range. I have installed the latest drivers from Intel but nothing changed. When i try to copy a file from my computer to the WD Network drive the transfer rates are very slow. I get Max 2MB/s - 3MB/s while if i connect my computer with a wire the speed goes up by 3-4 times more.
