I've got my 881 3g connection working. It's not the fastest connection but, I think it will work fo people who have no DSL or no cable service or as a backup. Pings from the remote office to the remote user PC average around 180 ms. Does that seem right? I was able to make phone calls and video calls to the Main Branch with a little latency with the video. Also had a WebEx going at the sametime.
I', using a Cisco antenna but, Is there anything else I can do to optimize the connection?
I have two PC's in my house. One server, one workstation. Both running Windows with Intel gigabit NIC's (82574L and 82579LM respectively). Switch is a Cisco 3560G. Being on a LAN, everything is < 1ms.
I get different speeds when doing a Windows copy between the boxes. From the POV of my workstation: Workstation sending file to server: 189Mb Workstation pulling file from server: 726Mb
From the POV of Server: Server sending file to workstation: 396Mb Server pulling file from workstation: 268Mb
Why is it so lopsided? I'm sure there are settings one can optimize in the Intel NIC drivers to bump up the speed.
Is WAN Optimization supported on Cisco ASA5520 Firewall and Cisco 3750 Switches. We need to add/enable WAN Optimizer functionality to make 3PAR data replication?
Release 6 controller 9 Mesh APs. 1524 (2x 5G radios, 1x 2.4G) and 1522 (1x 5G radios, 1x 2.4G) Designed for 3 linear hops and then a split to the rest.
AP1 = Root AP linear to AP2 Linear to AP3 Linear to AP4 equidistant to AP5 and AP6
The rest are further away from AP4, but have visibility back to AP 4 The issue is after an event (say a power outage) at AP4.AP5 uses AP3 as it's parent.That's okay during the power failure, but when AP4 comes back up, I want to force AP5 to switch it's parent to AP4.You may ask why, if AP5 can reach AP3 okay, it's okay to leave it that way.
So you can see it's desireable now that AP5 uses AP4 as it's parent.Over time, the system might figure it out, but our limited experience shows it seems to stick to the way it is.To complicate matters, sometimes we've found that it doesn't seem to reconfigure when the channel number has changed so AP5 can reach AP3, but AP4 (1524) comes up with a different channel on it's downlink radio.So, how can we force a mesh topology reevaluation/change for either 1 AP or the whole bridge group?I thought changing the bridge speed from "auto" to 54M (on AP3 above, for example) might force the attached children to rethink it, but it didn't seem to work (maybe I needed to wait an hour?).I also thought tweaks to "Radio Performance Profile" for radio might work. (not sure what to change, or how long to wait for a result)reseting APs and hoping they come back in a better topology is painful and slow.
I have recently been testing out the Kaillera netplay application thats embedded into a few old console emulators. Now the major problem is the de-sync between clients and I was wondering which is the best to reduce this.Say I have an upload speed of 1.2 Mbps and a download speed of 11.28 Mbps. Obviously, I am capped by my upload speed when it comes to changing how many packets i can send/receive per second because its all one setting and I am usually playing P2P.So, I am not entirely sure how big the packets are that are being sent, I am guesstimating based on what they said on Kaillera website that it is around 200-300 bits.Anyway, with my current upload speed I can transfer at a rate of like 600-800 packets per second depending on packet length.De-sync's happen quite often especially in the higher rom size games like Mario Party because of all the data being transferred. Would it be wiser to increase my setting of pps from 20 packets/sec to 60 packets/sec?
We have our Nexus as our default gateway (101.1) and the default VLAN1 is setup with two subnets 101.X and 102.X. The DHCP server is using a superscope setup to accomodate the overflow of devices requesting IPs on 101, so when 101 is consumed persons are able to obtain a 102.X IP address. The setup is basic on superscope. The issue is some times the routing to the firewall with a 102.X is not always 100%. Somedays all goes well and the 102 subnet is routed out to the firewall and its a good day. However, such as today a 102.X address is not routing as it did 24 hours ago. I am perplexed as to why this is behaving unpredicatable. Here is running-config for VLAN1 to show the 102 as secondary address to VLAN1.
I am having some difficulties to have a stable connection on a Cisco 881. I have a IP Sla running with an ICMP-ECHO towards the uplink router. Linked with this is a tracking on the IP SLA so I can shutdown an HRSP instance with the tracking. The desired result is with this that when the nexthop becomes unavailable HSRP switches to the second router with the backup connection.
Regardless whatever timeout or threshold, the tracking switches at a random point when the line is somewhat congested. Debugging it shows me only a time-out on the IP SLA.
Is there anything possible to get the icmp-echo to retry it 2-3 times or so before going it's status is set to failure? [code]
I currently have a network with (8) 2960 Cisco Switches. (6) of the 2960 switches are etherchanneled back to (2) 2960 switches in the computer room. I would like to setup QOS on the (8) switches, however the traffic is very differnt on each of the switches. I have video, ip phone, server, printer, PC traffic. I am not sure what the best method of separating this traffic into differnt QOS queues.
I have connected a Cisco switch ( SG 200-08) to a HP switch, everything works fine when have the HP port as untagged, but I can't get out when I tag the HP port. Maybe this is a HP problem but we can tag other ports on it to other switches.
Is it some setting on the Cisco switch i need to do? I have put 7 ports as access and one as trunk.
I tried to connect a 1841 to a Linksys with a static route. I am able to ping from a computer in the 1841 to a computer in the linksys network, but I can't ping from a computer in the Linksys network to a computer in the 1841 network?
I am trying to connect a cisco 800 series router using adsl to a bt router/hub. This didn't work at all - so the cisco router is now connected to the bt router using a switch and the adsl cable. When I connect my pc to the cisco router, it doesn't go on the subnet it's supposed to be on. it's set to the gateway on the cisco router and the pc is set to 192.168.3.252. The bt router is on 192.168.1.x. When I connect a pc to the cisco router, and assign an ip address e.g. 192.168.3.123 it doesn't have any internet connectivity, but when I set it to get the ip automatically, it gets the ip address.
I've a problem with my 871W. I can connect to the router by inside interfaces (LAN & WLAN) but not on WAN (Fa4). My client on the WAN is on the same subnet and I can ping 871.
I have a 1721 router installed with both an adsl wic and a 4 port switch wic card. My setup is as follows:
pc connected to port 3 (mode access on vlan 20) on the 4 port switch wic (installed in 1721 router)port 4 is configured as trunk (encap dot1q) and connected to fasethernet 0 (inbuild of 1721)fastethernet 0 configured with no ip address?
created sub-interface fastethernet 0.20 with encapsulation dot1q on vlan 20?ip address of sub interface 0.20 is 192.168.20.240?pc nic ip address is 192.168.20.245 however cannot ping 20.240?I want to use only this router with its switch wic for vlans and internet?
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 need to know about situation that i need connection between SFP+ with X2. i have 4849 E-F and it just support SFP+ and in other side i have 6509E and i can no find any Line Card with SFP+ Support and i should use 10G connection between them .
We have a new internet connection from DSL cisco router 800 Series (877).
You has been delivered it to us with Cisco Router 800 series (Ver 877), when we connect it to the PC directly it’ll work fine with the static IP.
We configured the OSPF between the Switch and the Router. and we can reach to the DSL router IP from our LAN any where. but we can't exit from the router to the internet.

I am installing a connection between Brocade MLX and Cisco 4503 using SE and SVI's. Below is the config for each. Am I missing anything like MTU Ignore or something along that nature?

I recently saw it for a good price online, and required a new router (had a netgear that died, and my backup was a really buggy Belkin which I'm currently using).I'm having an issue with the internet, in that when I connect my ADSL modem to the WAN port it seems to work fine, however the PC can't connect to the internet. When I go into the settings it says that the WAN connection is OK and even shows my external IP. I have it set via the stardard DHCP setup.Should I have done anything specific to my ADSL modem before plugging it into the RV180W? The Modem (D-Link 320B) also has a DHCP server on it, however I assume that this causes no issues when connected to the RV180W.
I have a SR520W-ADSL-K9, I´m trying to setup it trough CCA, but I have some troubles. At the internet connection I mark PPoE option, enter the vci=0, vpi=35, the username, the password (like the ISP TELMEX suggest), and mark the IP Negotiated option, but I have not find the ISP service give me an IP Address and establish the connection.
I have two 3560s that i would like to upgrade. But first i would like to make -absolutely- sure i dont wind up in a situation where i have to roll back over a console connection.to the day i still cant understand why oh why someone removed (or chose not to implement it everywhere) tftpdnld from rommon ;)
We have a new building where we added 3 network closets with 3750x stacks.We have 2 fiber gig ports connected to 2 microwave units and etherchanneled the to ports
We have the same setup at the corporate office except the connection is 2 fiber gig ports on a 6509. The 6509 is doing the routing
Now the problem is that we lost the connection to the management interface on only one of the three closets after a few days running. But some workstations at the corp office could reach it... others could not. The workstation were on the same VLAN. We solved the problem for a few days by shutting on of the fiber ports on the etherchannel. But is started happening again... now with PCs being installed at the new location.
The PC that was not working on the 3750x side could ping across to the 6509 but no further then that. It seems like an arp issue not routing because some devices are reachable and fully operational throughout the network.
Here is the configuration:

I have two WS-C2960-24TC-L Switch with Software Ver 12.2(25r)SEE6 with image c2960-lanbase-mz.122-35.SE5.bin and 12.2(25r)SEE1 with image c2960-lanbase-mz.122-25.SEE2.bin currently on it.
I want to enable SSH connections on the switches and believe I need to import the cryto image onto the switch. I would like to upgrade it to new version that can also support ssh connection but not sure which image to download from cisco. The switches are now live.

Company I work for just moved into a new location. We have two data closets which are patched as independent entities, with no Ethernet tie connection. These closets are roughly 100 feet apart.
There is a fiber connection that runs between both closets, that the previous tenant used to connect the switches. I have placed a Cisco 2960 switch in each location, and added one mini SFP gbic's to each switch. After attaching both sides, neither light up. I do a sh inter gig1/0/49 on each and shows 'down down' (not admin down).
What is the trick on getting these to communciate, do I need to configure these ports, and are they supposed to light up?
What I am trying to accomplish is to get the one closet that is completely cut off, communicating by logically stacking, or 'daisy chaining' via fiber.
I turned off the lights and popped the fiber out, and I do see a faint red light (I did not look straight into it), so I think the fiber is active.

My first time programming a Cisco ASA - Anyways I''m trying to setup up Ethernet 0/6 to be a DMZ Connection When I add port 0/6 to DMZ it gives me an error saying "The IP Address X.X.X.X /Subnet Mask cannot overlap the subnet of interface outside"So my question is I have an outside connection already configured - How can I make a DMZ connection with the same subnet mask with a different IP?
i have an OM1 MMF fiber run between two switches, the first being a 3750 and the second being a 3550.
The link currently exceeds the maximum distance for OM1 @ 1000Mb/s (220m) so i would like to downgrade the link to 100FX using the necessary SFP's/GBIC's to extend the maximum distance to 550m and run the link @ 100Mb/s.
I have the part code for the 100FX SFP to install in the 3750 (GLC-GE-100FX) but cant find a 100FX GBIC for the 3550, can I use a 1000SX GBIC (WS-G5484) for the 3550 at one end and the 100FX SFP at the other? Any success with this configuration over MMF?
