Can't Ping Between Routers (Packet Tracer)

Mar 6, 2011

I'm trying to set up a network comprised of three LANs connected by serial. As this is a small part of an assignment I've been instructed to subnet into /26 and to use /30 subnets for my serial connections.At the moment I can ping between devices on each of the LANs but I can't ping between routers at all. Embarrassingly I'm not sure why, I think it may be something I've missed on setting up the serial links as I have set routers up fine before using other connection types.

Cisco :: Simulate An ISA Server In Packet Tracer?

Jan 21, 2013

I'm an IT student and I've been assigned with homework simulating a network including an ISA server and some clients in Packet Tracer but I can't find anything which can be configured like an ISA (Internet Security and Acceleration) server(this is kind of Microsoft's technology as I know) in Packet Tracer, the generic Server from the devices box has only some basic services such as HTTP, DHCP, DNS, FTP, AAA, ... but none of anything related to ISA, all the servers in Packet Tracer have only 1 interface whereas the ISA server (as far as I know) should have at least two interfaces, and there is also no CLI supported for those servers so I think I can't simulate ISA server in Packet Tracer, can I?

Cisco :: VLANs Route Outside Of Network Packet Tracer

May 30, 2012

I am unable to get traffic from any VLAN to communicate outside of the router, as well as get any traffic from outside of the router to communicate with any device on either VLAN. I am able to ping the router from each device on each VLAN, and vice versa. However, the traffic seems to die at the router, and I cannot figure out why. I know it's probably a small, easy fix, but I cannot seem to find any kind of documentation on it.

I am trying to troubleshoot a problem where in one of my remote site is not able to access some networks at HQ over Site to SIte VPN ( asa 5505 at Remote and 5520 at HQ). I ran packet tracer and HQ ASA looks clean as everything came out as ALLOW. Remote site ASA packet tracer give me DROP out at Phase 9 (VPN). I am not very sure what to look in ASA for resolution now. Is it an access list that is blocking the traffice or VPN setup.

Cisco Firewall :: 5550 ASA (8.3) - Packet Tracer / Multi-Context Classification

Nov 22, 2011

I've been using packet-tracer for some time on and off with mixed results.
 
I'm running a multi context firewall with over 10 of the contexts sharing the same outside interface / network. All interfaces obviously have valid, unique IPs and also unique MAC addresses as mac-address auto is enabled in the system context.
 
This is an ASA 5550 running 8.3(2.10) interim so includes the fix for the well known packet-tracer classication failed bug.
 
So in theory, with firewall contexts on a shared interface the ASA should use the firewall MAC address to classify incoming traffic to the correct firewall and as far as I am aware, only fall back on using NAT to classify if the interface MACs are the same. In reality on my platform this doesn't seem to be happening and the classifier is using NAT to determine the destination context. I'm seeing this with live traffic (i.e. not generated by packet-tracer) in logs and can prove it by disabling certain NAT rules (there is some overlap with the IP addressing behind each firewall).
 
My question regarding packet tracer is this - in the above scenario with a shared outside interface, does packet tracer ALWAYS use NAT to determine the destination context? Or does packet tracer look up the MAC address of the ingress interface according to what context you are running packet tracer from? It appears that packet-tracer is using NAT in my case which could be just symptomatic of the potential bug I've described above rather than by design.

Cisco ASA 5505 Simple PAT - Packet-tracer Can't Look At Any External Devices While Running

Sep 16, 2012

here, am used to the RouterSwitch CLI but been asked to set up an ASA 5505 8.4.Quite simply I am trying to at least test out a static PAT from an external source to an internal server in a test environment and no matter whether I set it up as an auto-nat or a twice-nat whenever I run a packet tracer I end up with the same error. This is the packet-tracer I am running-packet-trace input outside tcp 80.80.80.80 3389 10.240.0.10 3389
 
Phase: 5
Type: NAT
Subtype: rpf-check
Result: DROP
Config:nat (inside,outside) source static server publicIP service RDP RDP
Additional Information:
 
[code]....
 
Now I have a couple of questions initially. I have made the presumption that packet-tracer does not look at any external devices while running - as in as long as the ports are up it doesn't matter what is on the end of them for testing purposes? Is there anything I am missing?I have this morning wiped the config and have simply set up the adapters, a default route and twice nat and am not sure why I keep getting the error. I am sure it is something very simple and I'm being a massive donut!

Cisco Switching/Routing :: 3560 Topology In Packet Tracer Related To Etherchannel Configuration

May 23, 2012

i have made a topology in packet tracer related to etherchannel configuration.i am using 2 3560 switches and 1 2950 switch. Now what i want is to bundle up the redundant links between these 3 switches. The links fa0/1-3 between 2950_1 and 3560_1 switches have been bundled up but when i try to bundle the links fa0/4-6 of 3560_1 to fa0/4-6 of 3560_2 it wont work. i am using channel-group 1 mode desirable between the 3560 switches. secondly if i want to assign ip to port channels then it has to be of same subnet between 2 3560 switches right and it must be same between 2950_1 and 3560_1. But these 2 subnets should be different from one another.

Cisco Switches :: ESW-520-24P - VoIP Packet Loss Every 35 Seconds

Apr 14, 2013

We have a customer running a Asterisk based Phone system, using Snom 320 phones and a ESW-520-24P as their switch.
 
Recently we have been confronted with an issue where every 35 seconds their is a very obvious drop of audio for both parties of a call.  We know it is not the phone system as we have run tests directly over the BT copper lines that have no drops what so ever.  Unfrotunately when we introduce the LAN in any way, we get the drops every 35 seconds.
 
We are running the whole solution on 1 vlan, yes I know probably better to use two, but the Cisco cannot automatically detect the Snom 320 phones to swap it to another VLAN, which complicates using a VLAN setup.
 
I really need to work out how to stop these packet drops, but I am new to the world of Cisco and dont really know where to look or what to try.

Broadband :: How To Fix Packet Loss On VOIP Programs

Jan 24, 2011

How do I fix packet loss on VOIP? Teamspeak, Skype, MSN Voice all have inbound jittery clipped robotic voice. Teamspeaks shows "total" packet lost, climbing to at least 20% with Speech packet loss 50-65% then I lose connection altogether. All other network programs (Firefox, streaming music, videos, online gaming) work fine.I have ATT DSL, using a Netgear Wireless G Router w/ built in Modem (model DG834G). The network has 1 attached device, my Dell laptop (which is usually powered off).The packet loss problem is identical on my desktop pc and laptop (both using the same network). Problem exists when nothing else is running, only Teamspeak (or another VOIP) I have replaced all wires, cables, filters. Power cycled modem. Problem exits with or without Port Forward.*running Windows 7 {64 bit}, AMD Phenom 8450 Triple Core, 2.11ghz [3gb RAM] Asus M3A78 Pro Motherboard

Cisco Routers :: RVS4000 Connects To ISP Can Ping And Tracer But Cannot Browse

Sep 22, 2012

Router connects to ISP but cannot browse the Internet. I have updated the firmware to 2.0.3.2 and that did not work. Reset the router to factory settings and that did not work either. Router had worked until the ISP changed the ONT. The router worked initally after the ONT was changed, but that changed sometime during the day as it did not work that night. The ISP gave me a netgear router and that works, so I can connect, but I would rather the RVS4000 would work. I assume a setting at the ISP, but do not know which one. I get an error on the computer "name resolution for the name dns.msftncsi.com timed out after none of the configured DNS servers responded" I can ping, tracert and my little weather gadget works, but a web page will not display

Cisco VPN :: 5540 - VoIP Over VPN

May 21, 2013

I have a Cisco ASA 5540 running 8.2(5). When I dial a phone on the other of the the VPN the first time I get a blank after it rings(i.e when the voice mail get activated if someone picks the phone up), however works the second and consequent times i dial.

A little background. Two sites A and B connected via IPsec Tunnel. No problems in communication except for the VoIP issue. A Phone in on site A(172.17.168.x) and other on site B(192.168.103.x). Site A and Site B is connected via an IPsec tunnel on the Cisco ASA. First call fails. Second call works. Result of a packet trace is also the same. The UDP packet get drops when tried for the first time but subsequent ones pass.

Cisco :: Configuring 2960 For VoIP?

Mar 26, 2012

We just purchased cisco 2960 for our VoIP needs and we are using polycom phones, and Phone and Computer will use same port. Since Polycom phones are capable working with CDP protocol and we are hoping to get another switch to expand VoIP network. I found easiest way of setting up each port is as following (from the cisco tutorial)

Switch#configure terminal
Switch(config)#mls qos
Switch(config)#interface fastethernet 0/1
Switch(config-if)#mls qos trust cos
Switch(config-if)#switchport voice vlan dot1p
Switch(config-if)#switchport voice vlan 10
Switch(config-if)#switchport mode access
Switch(config-if)#switchport access vlan 20
Switch(config-if)#exit

My first question,when we are using switchport voice vlan dot1p ,I thought we instruct the switch port to use 802.1P priority tagging for voice traffic and to use the default native VLAN (VLAN 0) to carry all traffic.Do I still need to create a Vlan 20 for data and Vlan 10 for voice ?

Secondly,same tutorial adds these commands as well,Do you think for our set up, using those commands are feasible ?

Switch(config-if)#switchport priority extend trust
Switch(config-if)#priority-queue out
Switch(config-if)#spanning-tree portfast
Switch(config-if)#spanning-tree bpduguard enable
Switch(config-if)#exit

Thirdly,when we get another switch and do the same configuration for the second switch, can I use any port on Switch 1 as uplink without doing any configuration ?
