Cisco Switching/Routing :: Difference Between 871W / 851 And FTP
Oct 10, 2012
I've acquired an 871W, because I'd like to use wireless, to replace my 851. I Ft Pd the 851's configuration to my FTP server and then Ft Pd this to the 871W. Save for the fact that this has a radio interface (currently shutdown), everything works save for FTP from the outside. I can not even telnet to port 21 of any of the internal FT servers. I can telnet to any other port (ssg, smtp, HTTP, https, etc.) but FTP will not pass. What's the difference?

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 an 871w set up to add wireless connectivity to an existing network. When adding a client to the physical interfaces to test VLAN internet connectivity, however, a DHCP address is assigned but internet traffic on the terminal never reaches the network nor does the network recognize the IP the terminal shows as being 'connected'. Also, pings sourced from the VLAN do reach destinations. I've attached my config file, I think it's a routing issue of some kind.
10.26.99.0 is the existing network. 10.26.99.1 is an existing 871w router set as the DHCP server for that network and 10.26.99.10 is a Windows Server 2003 DNS box. VLAN 2 and DHCP pool alpha were control sets for trialing DNS settings.

I've been trying to get my wireless configured for the past few days with no luck. I can ping every device on my local network and I can ping outside my network and surf the web. My wireless devices can see my wireless network but cannot connect to it.

We have a Cisco 871W working as PIX, controlling external VPN connections to our private network.The configuration is very similar to the one described here - "Cisco Router as a Remote VPN Server using SDM Configuration Example" url...
About once a week, it stops working, without aparent external intervention.The ping to the external IP stops answering, and the internal IP stops answering pings also.The solution is power-off and power-on, and it starts working again ...
What is the correct way to debug this situation ?I can connect a HyperTerminal using direct cable to the 871, but dont know the relevant commands to debug this situation.
Is there any LOG I can have a look into ? Yes, I am quite new to Cisco world .By the way : "show version" says Cisco IOS Software, C870 Software (C870-ADVSECURITYK9-M), Version 12.4(15)T7, RELEASE SOFTWARE (fc3)

I found a 851 router and tried to build a ezvpn tunnel. The issue I am running into now is that a 851 router can only have one vlan in its database. I need two vlans to go into the EZvpn tunnel with using another device. So can you tell me if a 881 router can have more than one vlan created on the router and can those vlans be assigned to a interface and can I create a svi for each of those vlans as well.

I have a cisco WS-C3750G-24TS with IOS flash :/ c3750-mz.122-ipservicesk9-25.SEB4.bin "
I purchased a new Cisco WS-C3750X-24 with the IOS flash :/ c3750e-universalk9-mz.150-1.SE/c3750e-universalk9-mz.150-1.SE.bin. ( NEW )
When i configured a stack between the two 3750, the new switch restarted due the version mismatch (different IOS´s);
We have two versions:
WS-C3750G-24TS-ipservicesk9 flash :/ c3750-mz.122-25.SEB4.bin "
VS
WS-C3750X-24 flash :/ c3750e-universalk9-mz.150-1.SE/c3750e-universalk9-mz.150-1.SE.bin.
Is that possible to configure a stack between then?

Switch A is: WS-C2960-48TC-S
Switch B is: SG 300-10MP
Neither switch supports a similiar transceiver module. We are looking at transceiver GLC-SX-MM for Switch A, and MGBSX1 for Switch B all the Layer-1 information (SX / wavelength, Multi Mode, etc.) I am able to find out about the two transceivers seems to match, so would there be any issue by having these 2 "different" transceivers at either end?

Are there any differences between the autoqos commands on a WS-C2960S switches (or in any other series)? Follow the commands:
- auto qos trust
- auto qos voip trust
I was checking the documentation on this link:
URL
And couldn't find any great difference between the two commands, as far as I could see they'll set the Ingress and Egress queues the same way.
Are there any differences between those two commands (auto qos trust and auto qos voip trust)? If so, when should I use one and the other?

what is the difference between Cisco Nexus switches and the usual catalyst 3750 switches.I do understand the operating system in both these are different.
When will we suggest using Cisco nexus instead of usual Cisco switches? Also what interface does Cisco nexus like 5548 come with , is it both copper and fiber?

Cisco let us try a CISCO C3750X- 24T-S Stack (2 switches) ->> IpBase Sofware licence We've 2 Hyper-v 2008 R2 and one SAN Netapp FAS2040 connected via Iscsi.All was working well with this stacks.Hyper-V see Nas Iscsi interface without problem. Even with basic stack config (no Vlan, ect...).Then, after this test period, we bought a C3750X-24T-L stack (2 switches) to replace the stack lent by Cisco.This one is LanBase Software.
With this stack, hyper-v work very bad ! We've got a lot of Iscsi error in the eventvwr.I can't access luns.So, is there a difference between LanBase and IpBase for a iscsi use ?I put the 24T-S config on the 24T-L switch without pb. So config is the same on both stacks...Also i've got a "TestPortAsicLoopback" = "Failed" on the new stack...I've tried with other stack cables. Not better.

WS-X4306-GB: 1000Base X (GBIC)
Whats the difference between these modules? I cannot find information about part number "WS-X4306" Do these modules (WS-X4306 and WSX4306-GB) work with SUP7-E?

I am a bit green with IOS and have exhausted everything I can think of with this. The router passes the WAN test in CCP?Undoubtedly there are probably a few things in the config that are either redundant or totally unnecessary, but I have been trying a few things to solve this with very little success.I have no security stuff in here because I have triewd to keep the config as simple as possible to start with. I will add that after I get the routing working.
Here is my most recent config:
Cisco871W#show config
Using 2631 out of 131072 bytes
!
version 12.4
no service pad
service timestamps debug datetime msec
service timestamps log datetime msec
no service password-encryption

I bought an 871w second hand with 124-24T IOS on it. I would like to enable QoS. When I use Cisco Configuration Professional to manage the router I click on QoS and it says it is not available. I know that the router itself is QoS capable.
This is my first time dealing with a router such as this and I wonder what I need to do to enable QoS.

I want to upgrade my IOS on an 871W. In order to do this I need to upgrade the memory. I have found that I need the MEM870-32F (Am I correct?).
As in here: {URL}. So if I follow these instructions: {URL}. Is that all there is to it?
