I just bought this switch off Ebay and I can't seem to find anything online on the physical connection of this switch. It's not like normal switches where it just uses a ethernet type cable that goes to serial, it requires a female to female cable which does not exist anywhere so I ended up buying a gender changer for a normal cable I had but can't seem to get the prompt to come up. I'm using 9600, 8 data bits, no parity, 1 stop bits and no flow control. Do some wires have to be crossed a special way or something or do I need to type anything special in the console to get the prompt? I can't find much online on this switch. At least not as far as serial connectivity goes.
I have a Cisco 3725 running IOS 12.3. I have three WAN connections (2 x 100Mb and 1 x 2Mb serial) and I need to replace the 2Mb serial connection with a further 100Mb connection. However, I have not got any spare 100Mb sockets.My plan is to use a switch that supports VLANs, connect the three WAN connections to the switch, each in their own VLAN, then connect the switch to one port on the router, configuring the switch port as a trunk (so that it passes all three VLANs across the link) and configuring the router so that for that single Ethernet interface, it has three subinterfaces each configured for a VLAN that matches the VLAN used for the corresponding WAN connection.
I am a bit rusty on my IOS so I wanted to run this all past the community for feedback. [code] Any thoughts on whether or not that will work? Are there any commands from the original interface configurations that I CANNOT use when moving them to a subinterface? I'm thinking that the speed & duplex commands need to be removed?
I recently installed a Dell 5324 switch as my main switch and it's my first time using a managed switch at home. One thing I've seen as an issue in a corporate environment, and now here, is that managed switches tend to take a bit longer for a port to be active. Ex: a PC is turned off, I turn it on but if the PC boots up very fast the port may not be ready. All mounts fail. This is the issue I am facing with my HTPC. It runs Linux and has a SSD, and it has no UEFI bios to slow it down (which is good, I hate UEFI for that) so it's up and running within 5-10 seconds of pushing the power button. The network mappings fail because the port is not ready by the time it gets to the script that mounts everything.
i'm making up a new lab and need to create a simulated serial wan connection between 2 routers. I originally did it with 2 wic1t cards but i sold my old setup. I have access to wict1 cards i know they are serial connections. will it provide the same function as connecting with wic1t cards?
I am a total new comer for Cisco Router. All I know is plug the console cable to a serial port on a PC, fire-up HyperTerminal to view and that's it. I don't know any command or scripts.
I am trying to setup my client connection, I already receive the required configuration settings from ISP. It is a Leased Line Serial connection.
How to setup the router with the below configuration.
Serial IP : 1.X.XX.222 Serial Netmask : 255.255.255.XXX LAN IP : 1.X.XXX.1 to 1.X.XXX.31 LAN Netmask : 255.255.255.XXX [Code] ....
i want to setup a temporary lan for gaming purposes in my school for a event but my school has only a free 8-port switch but i need to connect 10 pcs together i have a dlink modem but its kinda old its a dsl-2640t it has 4 Ethernet ports on the back and if pcs are connect to that they can detect each other.... can i brige the modem and the switch together.
Have been battling a router connection to new ATT t1 connection. Router was configured and sent from sister company to this new location. We have had ATT tech test circuit and it tests good, had cat5 cable tested from ATT to router, it tests good. I continue to get serial up/ line protocol down status though and cant communicate to it from wan.
I have a 5412zl 10.215.x.x/16 Most of the connections on this switch are on vlan1. B9 is the port which is connected to a Cisco 2821 Router. The port on that end is GE0/1. The port on the cisco side is not a trunk but configure with an ip of 10.215.1.30/24 Its part of a some ip access group. The network that i now sit on is a 172.x.x.x/24 (behind cisco router, about 3 hops to that main 2821)We current have a system on my side that talks to a server on the 10.215. that has no issues. I'm trying to access some switches on the 10.215. and have had no luck reaching them.
Here is the access list that i found that port is configured to use:
permit ip 10.215.0.0 0.0.255.255 172.18.0.0 0.0.255.255 permit ip 10.254.0.0 0.0.255.255 172.18.0.0 0.0.255.255 permit ip 10.215.0.0 0.0.255.255 172.14.0.0 0.0.255.255 permit ip 10.254.0.0 0.0.255.255 172.14.0.0 0.0.255.255 permit ip 10.215.0.0 0.0.255.255 192.168.2.0 0.0.0.255 permit ip 10.254.0.0 0.0.255.255 192.168.2.0 0.0.0.255 permit ip 10.215.0.0 0.0.255.255 192.168.20.0 0.0.0.255 permit ip 10.254.0.0 0.0.255.255 192.168.20.0 0.0.0.255 I would think the first permit would allow me to get through to the 10.215 side but maybe i need to set something up on the hp size to let it know how to get back? I'm very new to this stuff.
I am designing a cabling system to interconnect all the buildings in my school.In one of the building, I have 2 patch panels and switch to interconnect cables that comes into the building with cables that runs to the rooms.From what I understand, connectivity should be something like this:
1. Exterior cables coming in through the entry point. 2. Exterior cables terminates at the back of patch panel. 3. Patch cables run from the front of patch panel to a switch. 4. Patch cables run from the switch to another patch panel which connects the interior cabling that runs to the wall socket in each room.
My question:
1. Which ports should I use on the switch to interconnect exterior cable to the interior cable? They should be a connection between the exterior cabling and the interior cabling and both terminates in the same switch, but different ports. How do you allow communication to happen?
2. How do connect all the buildings to the router that connects to the internet?
How to properly power down the Nexus 5000 and the fabric interconnect switches? I have looked up and down cisco's and google web for steps, but they are all coming back with the answer to just disconnect the power cables after you have power down all the windows os and exs servers. Before i do that, I just wanted to make sure that that's the correct way to do it or if there are actual commands that I will need to run on the devices to properly power down. I know that the FI do have a command to reboot, but i need them to completely be power down.
Currently the OSPF network consist of 2 segment route via static route.One is AREA 0 and another AREA 10.Both network are seperate entity, only static route to route between 2 networks.But the static route do not provide the dynamically and flexibility, I plan to run routing between 2 networks via VLAN160 and VLAN162.
I still want to manitnace it was 2 different OSPFrouting domain.Can I run OSPF with differrent OSPF porcess ID?
can i use a cat 5 cable to extend a 9 pin serial cable to connect my PC to my home audio controller? I have a serial to USB converter but my PC is upstairs and my audio component is downstairs?
I think the crappy usb to serial cable from china broke because when i boot up my cisco router, after it decompose the IOS image and shows all the interface links, it won't do anything. I can't get to user exec mode.anyways, i think my usb to serial cable is faultily. I got one that is from ebay for like 2 bucks and i think it is the reason why i can't even connect to my router now
I have configured four E1 links between two locations on my 3745 using WIC-2T cards. At both ends all the serial links are configured as ip unnunmbered fastethernet 0/0 encapsulation ppp OSPF is enabled without CEF I would like to know how load balancing will occur in this scenario?Will all my links be utilised at the same time? Will multiple links be used only when the need (in terms of bandwidth) arises?
I understand that IPv6 uses the MAC address of a LAN interface to make up the EUI-64 of a serial interface since serial interfaces don't have MACs. What happens when there is no LAN interface available? What if the switch has only serial interface cards?
serial modem US robatics 5686G is not detected on windows server on serial port com1. i tried to restart the server . turn the modem on and off disable the com1 port reenable it again . update the firmware of modem on different workstation and connect it back to server ( couse it's working on another workstation so it's not the modem) i really don't know what to do is there a trick for this like in registry or somthing in mouse settings that mouse could actully detected on com1 and don't let the modem to show up on device manager? by the way modem cable is serial cable i tried to change the cable as well non of my ways works?
I'm based in the UK and am using a DIR-655 router but I have no record of its serial number (there is no sticker on the item, and the original box is now missing) - is there any way I can ascertain which version of the router I have? As I understand matters, I need to know this so that I can apply the correct firmware upgrade, which is what I wish to do.
Were bringing up a new site shortly and I'm trying to configure Serial0/0/0 which will be connected to an MPLS over 1.5m T1 line. I am basically doing a simular configuration as other sites where one of the ethernet interfaces is handed off from a fiber optic wan, but a T1 MPLS is connected to a WIC card and this provides a redundant path (though slower) in case of a fiber cut or equipment failure. This should be pretty straightforward but it appears as if I have no serial interface on this router. Card is in and everything, it is a VMIC-3-1MFT-T1/E1 in EHWIC 0.
i have LMS 3.2 installed in my campus. i need the serial number of the LMS suite to open a service request with cisco. but unable to find the same. How to find the same.
I know serial interfaces are called that because they put bits on the wire serially - i.e. one bit at a time. If that's the case for serial interfaces, how do other kinds of interfaces, such as Ethernet interfaces, put bits on the wire? Do they somehow put more than one bit on the wire at a time? I assume it's a faster process, but how so?
Any good way to force a serial link to delay packets to simulate a hi latency WAN link? Found this command so far:
Router(config-if)# transmitter-delay hdlc-flags
I can dial the speed up/down via clock rate all good but I need to also simulate latency. This is for simulating a WAN bonding scenario so I was going to aggregate a 10M ethernet port with a 2M serial and a 512k serial. But I need to also ensure varying latency.
HP just released the 8560p elitebook- not a bad shake and it actually has an integrated Serial port.Any other notebooks that have integrated serial ports?- I know the T6x Thinkpads used to use a slimbay adapter thing. I just hate the Usb adapter, and bossman said I could get a new computer here pretty soon...
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]
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.
