I need Know what connection is using on Cisco 2811 router.I have this interface in Cisco 2811, I need Know if this port is connected to Fiber or Copper. I think is copper with RJ45 but I see 100 base TX/FX so this make me doubt about it because TX its for copper link and FX for fiber. [code]

View 2 Replies View RelatedI have two Aironet 1242AG access points. Currently, one of those access points is in use with an SSID of ABCWIFI.
I want to extend the wireless network to an area that can't be reached by copper or fiber. So, I've purchased another 1242AG. What I'm not sure of is how to configure it. Should I use it as a repeater or in a root-bridge/non-root bridge configuration?
What I'm most confused about is, what do I do with the second radio? Do I use the 5Ghz as the "backhaul" with a completely separate SSID and then broadcast the normal SSID over the 2.4Ghz? Or, do I even use the second radio at all? The key is that the same SSID is used in all locations because the devices in use need to move seemlessly between access points
I have a WS-X6816-10G-2T module with X2-10GB-SR modules. I will be getting a SMF hand off and the length of the termination is around 100 meters. (I will be getting another hand off for Inter-DC link for which I have X2-10GB-LR module). The question is can I connect this SMF hand off (short length) on the SR module?
View 2 Replies View RelatedWe would like to setup a link to our DR site that is separate from our main network traffic. This link will be used by an EMC VNX SAN for replication traffic. The SAN will be plugged into a fiber port on a 3750 switch and going out from the same switch (going in as multimode, going out as single mode) into a patch panel that runs over to the DR site (about a mile away). At the DR site it will go from the fiber panel into another 3750 switch which ends up going back out of that switch into our DR SAN.
I'm wondering what the best way would be to configure the fiber ports to accomplish this. I'm affraid that the replication traffic will find it's way over through another route and congest our main network unless configured appropriately.

The problem I have is that we have issues connecting fibre to the HP switch, so I have decided to attached a CAT 5 to Fibre convertor at this end and another to the cisco switch.
My question you can not connect a HP switch to a Cisco switch, is this true or do I just need to confirgure something on the ports.

I have a laptop with a single physical NIC which I have used the advanced management tools to create two virtual NICs (say vlan 10 and vlan 20) and both are on the same subnet (say 192.168.4.x). One NIC is for normal TCP/IP traffic and one is for broadcast/multicast traffic (I have some custom software that requires this to be the case and works fine on an older laptops with built-in physical NIC and PCMCIA XIRCOM NIC). The dual NIC laptop communicates with a dual NIC server via a Cisco 2811 router (which has a 16 port switch module at the back) and has vlans set up so.
What I want is for the single NIC laptop (with two virtual NICs) to be able to also communicate with the server. Basically, one NIC is for normal traffic and one is for multicast/broadcast traffic. All three machines need to be able to talk to each other using the NIC for normal traffic and both laptops must be able to receive broadcasts from the server. What is the best way to configure the router to handle the trunking/tagging? Most configuration documentation I read has two complete subnets for the two virtual NICs. Note that all three machines use static IPs and are part of a workgroup so no DNS and domain servers etc.
We need to deploy a 3750X switch with 10 Gb module. The pb is what SFP to choose ? The 10 Gb ports will be attached to an ethernet 10 Gb RJ-45 Server port. The 10 Gb connection has to be copper (not fiber). Is this reference ok : SFP-H10GB-CU3M= (version 2) ? I mean is it a copper cable with an attached SFP.

I have made a routed port on 3560G Switch and defined a pool 172.28.4.62 255.255.255.192 and connected to E1 converter RAD (4E1 to 4 FE) the E1 media is through Microwave on the other end same E1 converter is connected through layer 2 switch and defined a pool as of routed port configured in 3560G switch.
The port is generating lot of giants and after a while it also distrubs other routes ( Port1 to Port 16), configured with Vlan11 and port 22 as routed port.I have checked the routed port through wireshark the maximum frame size is 1514 and configured the MTU to 1514, giants are not showing any more but after 10 to 12 hours switch gets hang. Either to shut the port or to reload the switch to get switch and other layer routes to be normal.
I have checked speed and duplex settings same as E1 converter. Full duplex. 100 Speed. Why switch is not behaving normal. If I shutdown the routed port it is normal.

Any method of forcing a non connected switch port LED to blink for a certain number of times regardless if there is anything connected.The purpose of this is we have remote 3750 switch stacks and quite often have to tell non technical staff to patch to a certain port. It would be much easier if we could say "Connect it to the empty port which just started blinking orange" as the port numbers are difficult for them to see in these locations.A similar feature is available in the ethtool package for linux which makes it really easy for identifying ports on servers. It would be great if a similar feature is available on Cisco switches.
View 2 Replies View Relatedshow cdp neighbors command shows two devices connected through the same local port?I have a Cisco 3560 that when I issue the "show cdp neighbors" command I get the following results: [code]
the question is why is this showing that Gig0/3 is being used twice to connect to two different devices. I have verified there is no hub connected to this port and in fact Switch3 is not connected to Switch1 at all yet it still shows up in the CDP table.
I have cleared the CDP table on every device at this location and still get the same results.
One of the ports on the 3750 stack was configured for VLAN121. It was changed to VLAN40 and the configuration saved. Both VLANs exist in the switch configuration. As soon as a host was connected (in this case, a label printer) the port VLAN reverted back to VLAN121.

The switch is configured with about 10 vlan and it is a inter vlan routing, a default route is configured in the switch where the gateway is the firewall.
