Cisco Switching/Routing :: RV120W Blocks DSL Modem Configuration?

Nov 9, 2011

I work for a small pharmacy that uses a Cisco RV120W router to separate hospital VPN traffic from general internet traffic. The VPN traffic is redirected to a dedicated T1 line (Or T-something, I wasn't involved in the actual setup of the VPN) connecting our store directly to the local hospital, and general internet traffic gets redirected to a ZyXel PK5000Z DSL modem (We have Qwest/CenturyLink 7m/768k). The DSL modem is running the latest version of our ISP's custom firmware.
 
Prior to installing the VPN and RV120W, LAN traffic was handled with a basic D-Link DI-604 wired router. The router itself was configured with an IP of 10.100.100.254 (With all LAN clients assigned DHCP IPs in the 10.100.100.XXX range) and "WAN" IP of 192.168.0.4, and the modem configured with a LAN IP of 192.168.0.1. The router was connected from it's WAN port to one of the LAN ports on the modem.
 
The modem has it's own built-in router, but the store owner wished to have an "extra layer of protection", so to speak, and had the D-Link router installed to serve that purpose. Prior to connecting the VPN, a second router was admittedly redundant and unnecessary. However, now that we have the hospital VPN, a second router is REQUIRED to properly separate the VPN traffic from other internet traffic, since the router built into the DSL modem doesn't have the capabilities to perform this task (We had already attempted to operate the VPN over DSL...it failed miserably and spectacularly. A dedicated T1 was the only reliable option).Anyway, when installing the RV120W, we duplicated every possible setting from the old router, including configuring it with a LAN IP of 10.100.100.254 and a "WAN" IP of 192.168.0.4 and connecting it in exactly the same fashion as the old router (Modem LAN to Router WAN). Essentially, the RV120W was set up exactly the same as the old D-Link router, just with the added VPN functionality.
 
The problem is this: ever since installing the RV120W, we are no longer able to access the DSL modem's administration page (http://192.168.0.1). We were able to do this without any trouble whatsoever with the old D-Link router, but the RV120W seems to be blocking it somehow. Any attempt to load the modem administration page just forever sits at "Waiting for 192.168.0.1...". It never times out, it never shows any error messages. It just sits there, forever trying to load the page, showing nothing but "Waiting for 192.168.0.1..." at the bottom of the screen.
 
Now, we know for a fact that it is NOT a problem with the modem, because if we connect a computer directly to it via ethernet (Completely bypassing the RV120W), the administration page loads perfectly fine. And, admittedly, we could configure the modem in this manner whenever required. HOWEVER, the modem is located in a rather inconvenient location (In the ceiling, sitting on top of a ceiling tile), and having the ability to remotely manage it like we could before would definitely be something we want to be able to do again...especially since there are plans in motion to install new pharmacy equipment that will require us to do a ton of "trial and error" configuration to the modem.The RV120W has been updated with the latest firmware, yet the problem still persists.

Cisco Switching/Routing :: Catalyst 2900XL Blocks PC?

Jan 21, 2012

I try to insert a picture, to make the situation easily understandable.
 
The problem: After I have connected one more PC to the unmanaged switch, it cannot connect to network neither by DHCP IP, nor Static IP. (Physical Link is Ok, but no communication)
 
Tests made:
 
- PC1 turned off, to test connection, but PC2 cannot connect

- portfast has been turned off on the port of Cisco (which connects to Mediaconverter), but PC2 cannot connect

- PC2 has been reinstalled, replaced, other network adapter has been inserted, but cannot connect.

- the unmanaged switch has been replaced to a new one, but no success.
 
PC2 can connect to Cisco only if connected directly to RJ45 port of D-link Mediaconverter. But this is not a solution, because in that office, I would need for both of the PCs.  
 
running config of the switch:
 
System image file is "flash:c2900XL-c3h2s-mz-120.5.2-XU.bin"
cisco WS-C2924C-XL (PowerPC403GA) processor (revision 0x11) with 8192K/1024K byt

Cisco Switching/Routing :: SR520-FE-K9 Initial Setup Blocks HTTP

Sep 4, 2012

I have a fresh SR520 that I only did two things to it using CCA 3.2(1):
 
1.  Assign the address of FA4 to be 1.23.456.90 with a mask of 255.255.255.252
2. Declared a static nat of 1.23.456.90 port 80 to 192.168.75.12 port 80
 
I connected laptops to two ports:

1. FA0 (DHCP assigned laptop the address 192.168.75.12)
2. FA4 with the address on the laptop set to 1.23.456.90 and mask of 255.255.255.252
 
This is an exercise to simulate a cable internet configuration I will install the SR520 into.I can ping and point my browser to 1.23.456.89 and access the web server running there on port 80 via the inside laptop.I CANNOT point my browser to 1.23.456.90 from the outside laptop and make a connection. 
 
What I am doing wrong with NAT?  (I believe the problem lies therein as I did even try telling CCA to delete the firewall and I still could not connect to the inside web server).I have a network monitor (Wireshark) on the inside and see nothing coming across.  I THINK I see successful NAT translations in the NAT logging (also in the attachment).

[Code]....
 
Now, I need to be able to reach the server (192.168.1.100) from a PC on LAN #2 with IP 192.168.2.50. So, I've created au static route on Office Router #2 (192.168.2.1) because of course it doesn't know how to reach private subnet 192.168.1.x. My static route looks like this :
 
192.168.1.0 / 24 (Destination network) --- 192.168.2.254 (Gateway) 

...but it doesn't work, no ping. When I do a tracert to server IP (192.168.1.100) from PC on LAN #2 (192.168.2.50), the result is :

1st jump ---> 192.168.2.1
2nd jump --> 192.168.2.254
...and it doesn't go further.

Cisco Switching/Routing :: MGF Configuration 1941W

However, i'm noticing that my lan to lan network performance is very slow. Peaking out about 3mbs. I was reading some documentation that suggested MGF (MultiGigabit Fabric) might resolve this problem.
 
I have a basic setup in my test environment trying to emulate a branch deployment. 1941W connected to a access switch (3400).

Cisco Switching/Routing :: SG200-50P And PoE Configuration

Jul 17, 2012

I currently work in the IT field part-time as a end-user support technician while I am finishing my Bachelor's Degree in Network Administration.  I'm not completely new to networking at this point, but I am by no means a master of it either.  The basics of small networks (less than 10 PCs) and the lower-end of small business grade Cisco equipment are not unfamiliar to me.  Up until this point however, I have had very little experience with any higher-end Cisco networking equipment.
 
Now on to the questions, which may seem like the answers should be obvious, but let's face it, I do not have the resources to own much equipment myself at this time for experimentation purposes, nor does the school I am attending have a lot of financial resources to provide us with recent hardware to learn on.  What I want to know are a few things about PoE as implemented on Cisco devices, specifically the SG200-50P small business series switch.  According to the technical documentation, the switch supports PoE on 24 of its 48 ports, specifically 1 - 12 and 24 - 36; simple enough.  The switch is currently installed in an office that has less than 24 connected devices, but that is currently expanding.  None of the PoE ports are utilized as of yet, but going forward, there will be more than 24 connected devices.  Will another switch need to be installed if the additional connected devices (PCs and printers) are not using PoE, or is the PoE an auto-sensing feature that will simply remain disabled if a device that does not require power over the network cable is connected?  Is there some setting that needs to be changed through the management interface to keep devices that should not be drawing power from doing so?
 
There will likely be some additional questions generated by my inquiry, and I fully understand if these are completely novice questions, but I admittedly do not know the answer.  When I Googled it, I was greeted by a few hundred thousand results, the first dozen or so pages of results all being for places to purchase this particular type of switch, so I thought I would try my luck on the forums of the place that made it.

Cisco Switching/Routing :: 891 Initial Configuration?

Jan 9, 2013

On a recommendation from a network engineer, I got a used Cisco 891.  Having worked with small business routers most of my working life, I thought this should not be a problem.  However, I had no clue these things used a console and command line to initialize.  I have the console cable, am able to console into the device, but am haphazardly issuing command lines straight out of the PDF manual but cannot get Cisco CP to discover the device.
 
From what I can tell, I am stuck at the point where the manual tells me to enable http server.  I ran the command lines several times, executed write mem where available, but when I run the show services command, http is not enabled.
 
And if you do refere to command lines, I was reading some other forums and they were speaking of "run this command, run that command" but I could not make out the correct syntax, in what mode, whether it be config or config t, etc.  So I might need a wee bit of handholding.
 
I'm hoping that once I can get Cisco CP or CPE to discover the device, I can make my way through the GUI to configure since those usually do make sense to me.  As of now, I'm in the thick of it ...

Cisco Switching/Routing :: SG300-52 - CLI Configuration Option

I am trying to configure Cisco SG300-52 switch for the first time and stuck without CLI configuration option. The configuration can be done using GUI, however, configuring using CLI would be more comfortable (as I am used to work with CLI of other Cisco switches)..
 
I was able to lo gin to switch using SSH, but the CLI appears in MENU format and was not able to find any way to go to CLI mode.
 
As per some blogs, in SG300 switches CLI mode can be accessed using Ctrl + Z in Menu, which did not work either in my case.
 
Switch is running with latest firmware version Sx300 Firmware Version 1.2.7.76.

Cisco Switching/Routing :: ESW520 - VLAN Configuration

May 2, 2011

I have a headquarters office that has recently bought a new voice system.
 
We have a site to site connection from the head office to 3 remote offices. All have ASA5505 firewall.
 
I have created 2 interface on the ASA5505: 1: inside with vlan1 and switch port port12: voice with vlan100 and switch port port2
 
Port1 on the asa goes to port 23 on the switch for vlan data
Port2 on the asa goes to port 24 on the switch for vlan voice
 Port23 is member of vlan1 data

I added vlan100 to port 24 but by default vlan1 is member and i can't remove it. Its greyed out
 
All ports on the switch are member of vlan1 and vlan 100 because the port on the switch goes to the phone and from the phone there is a port that goes to the PC. Phones are getting addresses, and PC as well.
 
I am having a kind of loop because there is 2 exit for vlan1 (port 23 and 24) and that's slowing down my system and sometime i loose the connectivity to my servers.
 
When i do a show arp on my asa, i do see that some IP are beeing learned on the wrong interface. some PC addresses 192... are on the voice and some voice IP 10.10... are on the inside.
 
I am pretty sure that the problem comes from my switch configuration.

Cisco Switching/Routing :: 850 Not Saving Startup Configuration

Jan 18, 2012

I have a Cisco 850 router that whas having problems getting an ip address via DHCP. I did some stuff on it but that didn't work, so I rebooted the router to go back to my last saved startup config. When I turned it back on and connected t othe CLI console I got the "Would you like to enter the initial configuration dialogue?" message. Thinikng I just forgot to save anything to the startup config I went through the initial set up again and made sure to save everything to the startup config. After going through the intial config and setting up a vlan to assign DHCP to clients I saved the config and rebooted, upon reboot and connecting to the CLI console I got the same "Would you like to enter the initial configuration dialogue?" message. Tryign the setup once more and making sure everything was saved to startup config I rebooted again just to make sure the changes would stick, and sure enough they didn't. Whay is the config not saving to the startup config?
