Cisco Switching/Routing :: 3560 Command Shows Two Devices Connected Through Same Local Port?

Oct 14, 2012

show 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.

Cisco Switching/Routing :: 3560G Can Ping Devices In Enterprise LAN But Cannot Ping Interface

Mar 31, 2012

I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.

Cisco WAN :: Devices Connected To 1941w Router Cannot Ping

Sep 18, 2011

I have a copper over ethernet connected to an adtran 908e connected to an ASA 5505 with a port 192.168.150.254 connected to the router on the Gigabitethernet 0/0
 
I can ping to internal and external ip addresses but when a device is connected through the wireless signal then the device cannot ping anything; what could be stopping the device from pinging any ip addresses internal and external?
 
I posted my current config for the router and ap:

Cisco Switching/Routing :: 1921 / HSRP - Cannot Ping Any Of VLANS

Jul 13, 2012

I have configured HSRP with InterVlan routing. All communication is flowing properly between the vlan's on Router A but when I test failover to Router B I cant ping ANYWHERE. I cannot ping any of the VLANS.

Also, From the primary router I cannot ping any of the interfaces on the secondary router.

I have 2 Cisco 1921 Routers configured for HSRP. Both the G0/1 ports plug into a Cisco 2960S 48 port POE switch (STACKED) (port 1 and port 2 which are trunked and allowing all vlans to pass through. And both of the G0/0 ports are plugged into a Cisco ASA5510.

I have attached a diagram of the setup and the interface configs of the routers.

Cisco Switching/Routing :: 887 - How To Restrict Devices Connected To 800 Series Router

Jan 30, 2013

I have a Cisco 887M router which I wish to restrict the devices allowed to be connected/allocated an IP address to two, and *only* two.
 
I can't, for the life of me, find out how to allow these two devices to connect to ANY port - I can configure a MAC restriction on a single port, but I don't know how to make it so that I can allow JUST these two devices to connect to any port in the 4 port switch/VLAN (VLAN 1 is used because the mongrel who set this up was lazy). I know the MAC addresses I want to allow
 
How I can do this? I *can* restrict any given port to the two MAC addresses - but if I try to add the MAC addresses to another port, they get removed from the initial one. I need to be able to have them connect to ANY port and work, but allow NOTHING else to work.
 
For those wondering, this is to counter a user who is utilising company resources for purposes not approved - and costing us quite a bit of money in the process.

Cisco Infrastructure :: 1921 - Set Up Router To Provide Internet Access To Local Network

Feb 6, 2013

I've been trying to set up my new Cisco 1921 Router to provide internet access to my local network but with no success. I've been reading guides and looking at videos and I have to be missing something becaouse I can't access internet (ping/tracert) from my local network.
 
The DHCP server works fine and the clients on my local network gets ip-adresses from the router but can't ping or tracert outside the local network.

Cisco Switching/Routing :: Add N2K To Existing N5K - Can't Ping Devices

Mar 5, 2012

I have several cabinets with top-of-rack N2K's attached to N5K's via FEX's.  9 cabinets with 2 switches each. 
 
Recently I added 3 more cabinets to the mix, for a total of 12 cabinets with 2 switches each.
 
I can get into the new switches and see the FEX's and configure ports, etc. but no device I attach to the 'new' N2K's is pingable over the network.  I can take the same device, same cable, and attach it to a legacy N2K talking to the same N5K's, and it immediately joins and is pingable over the network

Cisco WAN :: 2800 Can't Ping Directly Connected Devices

Mar 28, 2013

I'm trying to configure a 2800 series router. .I'm consoled in and put a basic config on the router (see attached). After putting this basic config on, I plugged it into a small unmanaged switch, changed my laptop's IP and plugged it in the switch also. I can't ping the router from the laptop and vice versa. This is the second switch I've tried this with, so it must be.The first switch, I installed at location, connected a cisco cable to it and a local server, so i could remote in and finish configuration. In that scenario, I had plugged the switch into a managed switch and had the same result as I'm getting now--can't ping IP addresses (can't ping the switch's IP, not can it ping local IPs).

Cisco VPN :: 1921 - No Local Network / Internet While On IPSec VPN

Dec 28, 2011

I am testing a EasyVPN IPsec server set up on a cisco 891. Here is how I have it set up right now- the 891 is connected to our backup internet connection (different ISP from our main line) and we have a cisco 1921 as our production router.
 
I am experiencing a problem where when I am on our internal network off the 1921 and I connect to the VPN on the 891 I lose all local network connectivity. Nothing works, can't ping, can't telnet to the 1921, can't browse the internet, its not just DNS either.
 
I believe the issue lies in the configuration of the IPSec server on the 891 because when I connect to our client's cisco IPSec VPN I experience full local connectivity with no issues whatsoever. It seems to me that ALL traffic is being routed through the tunnel.
 
Other than the local issues the VPN is working fine and I can remote desktop to the PC I have set up off the 891 and telnet to the 891 from there.

Cisco Switching/Routing :: SG300-10 See All Traffic From All Connected Devices On Any Port / Where To Connect Listening Device

Dec 20, 2012

In my LAN environment, I'm using two cisco SG300-10 switches. Both switches are connected by GE10 on both switches, where both ports are set to trunk.Now on all ports 1-9 on both switches, I'm having client computers attached. So I set ports 1-9 to "access" mode.All interfaces on any switch is left in default vlan.
 
Is it normal that I see all traffic from all connected devices on any port where I connect a listening device?What I'd like to achieve is, that only traffic that is meant for a specific workstation is actually forwarded to this workstation. By now it seems that I get all the traffic from everybody.

Cisco Switching/Routing :: Ping Break Between ASA 5550 / 2911 (directly Connected Via Ethernet)

Aug 15, 2012

we have the following setup for our network :
 
UserNetwork - ASA5550 - WAN Router 2911 - ISP Netowrk - Branch Routers 877s / 1941s
 
Since last week we started noticing this problem that the branch users started to complain of slow application response.. After verifying it with the ISP and middle network we noticed that if i ping from my machine (ie usernetwork) to the WAN Router interface (facing the ASA) , i get time outs..  which is strange cause this is directly connected to it via ethernet cable.

Linksys Wireless Router :: WRT160N V3 - Network Crashes When No Devices Are Connected?

Nov 6, 2011

For a while now, my wireless network at home has been very unreliable. I posted on these forums before, asking for assistance to fix crashes that seemed to be random. I was largely unsuccessful, and the problem continued. However, as I continued to experiment with different methods to keep my network up and running, I noticed that as long as I had at least one device connected to the network around-the-clock it never crashed. This was easy enough, as I own an iPod touch and a dock (I would leave it sitting it the dock unlocked all the time). But it's annoying to never be able to leave the house with it, and I'm ready to finally get a solution to the problem once and for all. I would prefer not getting a new router, but if worse comes to worse I will.

To sum it up:
 -Works perfectly (when up) at full speed, never crashes unless there are no devices connected to it.
-When it does crash, it is very difficult to 'coax' it back into working again; it's been down for weeks at a time before.
-For some strange reason (and maybe this is a clue), newer game systems such as a Nintendo DSi or PS3 can make it start working again. I, of course, own neither of these.
-I'm using a WRT160N V3, latest firmware as far as i know.

Scanner Doesn't Show Up At All In Local Network Devices

Nov 12, 2011

Im working for a client at the moment and I've had to setup a network printer for them, I've got 4 Windows 7 machines easily printing over the network to this printer that is connected wirelessly but they want one of there machines to use the scanning functionality of the printer.The scanner doesn't show up at all in the local network devices like the printer does and to be honest i don't really have any experience with scanning over a network to a windows 7 machine, but this printer does support scan to ftp so my idea is to setup a small ftp server on the windows 7 machine with a folder to stored scans on the desktop or something, then put the details of the server in to the printer making it as easy as possible for the customer to scan stuff and just get it from the folder on the desktop, i could also share this folder over the network for anyone to open and get a scan if needs be.

D-Link DAP-1522 :: Devices Local Do Not Show On Network Map

May 17, 2011

This is the configuration I am running:Internet > Cable Modem > Netgear WNDR3700 Router ~~ DAP-1522 > Wired Windows 7 PC + Linux PC + Printer.The Windows 7 and Linus PC's do communicate well to the internet as do any laptops accessing the router wirelessly and any devices wired to the router. That is the good news.

The bad news is that any devices located after the DAP-1522, including the DAP-1522 do not show up on the network map of either the router or any of the wireless laptops. Neither does the Win 7 PC connected through the DAP-1522 show any networked devices, whether through the DAP-1522 or not, even though network discovery is turned on.

Right now the DAP-1522 is set up to function as a bridge and is in "Static IP" mode. I tried changing it to DHCP, but the DAP-1522 will not allow saving that setting, even though it will allow changing it. It just reverts back to "Static IP". The firmware version is 1.31, and the firmware update went well after a workable logon to the admin page was discovered. Also the one-button (WPS) set-up to the router worked as far as allowing an internet connection.

What needs to change to allow all the devices to show up on the network maps and maintain internet access? Ultimately, I would like to stabilize the IP's of the major components of the network to make troubleshooting easier. But to do that the devices need to show up on the network maps, particularly of the router, so they can be added to the IP reservation table by selection.

Cisco Switching/Routing :: 1921 - Router Recommendation Based On WAN Throughput

May 21, 2013

I'm trying to identify a Cisco router that will give 300+Mbps through a 1Gb WAN port.  I think the 1921 can get up to around 300Mbps with the on board RJ45 ports, but are there any other/better suitable models?
 
There's no need for any other particular functionality or feature set, the routers aren't doing anything fancy or unusual - it's the achieved throughput that's important.

When Connected To 192.168.50 Network Cannot Seem To Ping?

Dec 7, 2012

The issue i was having is when i connect to 192.168.50.* network i cannot seem to ping or connect to 192.168.51.2 (esxi host1) and 192.168.51.3 (esxi host2) and also free nas device i.e 192.168.52.2. i can only connect to these devices if i ping the 192. 168.50.1 from both the esxi hosts and also from free nas. Everything starts working if i ping from the esxihosts & Freenas device to 192.168.50.1.

f i connect to the hp procurve switch i can ping the hosts fine from the switch not when i connect to Draytek Router i.e 192.168.50.1 unless i run a ping from esxi hosts and free nas device then everything starts working.Here is my network setup for my ESXI home lab.

I have Draytek Vigor 2800 Router with ipaddress 192.168.50.1 (This Router is Downstairs and connected to DSL Line) and another Router with Firmware flushed with DD-WRT and IP address for this is 192.168.50.2. (this router is in upstairs labroom and is connected in Wireless Bridge Mode to Draytek Router Downstairs)

There is a HP Pro curve Switch 2610-24 with IPaddress of 192.168.50.3 and has VLAN's configured on this switch.The VLAN's are : VLAN10 is esxi vlan and ipaddress is 192.168.51.1 and vlan20 is storagevlan and ipaddress is 192.168.52.1 and vlan 30 is internet vlan and ipaddress is 192.168.50.3 (Switch Address).Port 24 is untagged to vlan 30 i.e internet vlan and connnected the port to dd-wrt router lan port. I have untagged ports 1 to 5 to vlan10 i.e esxivlan and connected esxi host's 1 & 2 to ports 1 and 2 respectively and connected freenas device i.e storage to port 6 which is untagged to vlan20 i.e storagevlan

IP Routing is enabled on the switch and ip route 0.0.0.0 0.0.0.0 192.168.50.2 and Default gateway on the switch is 192.168.50.1.

On the Draytek router i have configured a static route for 192.168.51.0/24 and Default Gateway is 192.168.50.3 and another static route 192.168.52.0/24 and default Gateway is 192.168.50.3

Cisco Switching/Routing :: C3560 Swap Out Not Ping Across Network

Jun 17, 2012

Had a switch die over the weekend, a c3560, per our normal procedure I pulled the hardware put a very basic config on it(vlans, portchannel, uplink ports, ip of management vlan, con and vty security, snmp, enable secret, and hostname).  Then I use solarwinds orion to upload a copy of the old config to bring the switch back to the same state as the one that failed.  Its a system that has worked for us 3 or 4 times in the past.  But this time when the base config was on the box it couldnt ping across the network.I have tried clearing the arp cache and the dynamic mac tables, i verified the routing tables and even removed the 10.1.185.128/27 route and re-added it, saw the routing update go across to the other 65k, tried bouncing the edge switch(i cant bounce the 65k's), took down the po between the edge and 65k.
