Cisco :: (Received Encrypted Packet With No Matching SA / Dropping)
Jun 24, 2011Got to set up a site to site VPN to one in a clients office and we're struggling to get Phase 2 working, just seems to loop around saying "Received encrypted packet with no matching SA, dropping" which to me means the ACLs arent mirrored correctly?

Dec 8, 2010We are working on taking a port off of a switch and connecting it to a mux (TAC 900). Port is trunked to another switch in another geographic location. From wht I am being told from the engineer who handles the transmission end of things he said once our segment is physically connected the mux will crash. He supplied the error code to the vendor and they said it is crashing because of a jumbo packet in excess of 1536 bytes. Soon it will be a moot point as the hardware will be, upgraded but we need tis running NOW.

Mar 27, 2012We have Cisco IP phones behind a 2600 series router:Most of the time when the PBX receives a packet from the phone, the source IP of the packet is set to the public IP of the router (1.2.3.4) as expected. However, once in a while, we get packets (at the PBX) with the source IP set to the private IP of the phone (10.0.0.12).The router is configured by our provider, and they can't give us any explanation for this behaviour. Is it safe to assume that PAT is not configured properly at the router?

Jul 5, 2012I have a ASA5540 firewall set-up with an interface MTU of 1500.
I suspect that we are receiving packets with a larger MTU but have not found an easy way of confirming this. Any command that can be run on the firewall to display the MTU packet size being received on an interface?
We are also running Solar Winds so could query an OID if such a variable exists.

Cisco Switching/Routing :: 6509 Monitoring Session Experiencing A Large Packet Loss
Aug 16, 2012I have been searching the message boards and wasn't having much luck. I am running some monitoring sessions on my 6509 and on the VLAN I am monitoring, I am experiencing a really large packet loss. If we hook up a laptop to the destination port and run wireshark we are seeing between 80% and 90% packet loss. I dont see the packet loss on the show port command, but I do on the show int vlan command.
The config is as follows:
Session 2
---------
Type : Local Session
Source VLANs :
RX Only : 500
[Code].....
I was doing some reading on Egress vs Ingress and I am wondering if the Egress SPAN replication state could be causing the packet loss that we are seeing or does the ingress & learn command override that?

I have enabled snmp and netflow config on my router(2911) but not receiving the netflow packets are not reaching the server for due to some strange reason whereas other packets like ICMP for snmp are reaching the netflow collector.Finally,I created GRE tunnel between the two locations routers and set the route for the netflow collector/server to the tunnel other end IP. In this way the netflow traffic are reaching successfully to the server.

Jan 20, 2011When i check the status of my Internet Connection I notice that the sent and received bytes keeps increasing. I'm sure there are no downloads taking place that I'm aware of. No torrent clients, no antivirus nothing. I checked my PC for malware but that didn't work. As a result of this, i keep getting high pings in online games and can't even watch videos in youtube anymore. like, some software to monitor all the programs that use the itnernet connection without my knowledge or something??My primary concern is gaming (Call of Duty 4) so I wouldn't mind this idle downloading (whatever it is) as long as the major chunk of my internet connection is directed towards Cod4!

How Does The Router Find The Type Of Message It Has Received
Nov 5, 2011I know that the routers communicates using routing protocols and that they forward the ip packets. So I looked in the IP header and the RIP header(for example) and I don`t understands when an packet comes in how does the router understands it`s type? (There`s no byte field to tell him explicitly that this is an ip packet or a rip message)

View 1 Replies View RelatedProtocols / Routing :: No Packets Received After Reformat?
Sep 13, 2012I have an Acer Aspire one that connected perfectly to the internet until I did a reformat. Now it only works if through a wired connection or if the internet does not have a password protection. I have tried on 2 different locations with secure wireless and both have the same result. Packets are sent but not received. All other devices in either location are able to connect to internet through wired or wireless connections.IP address is at 192.xxx and DHCP is enabled, TCP/IP is set to obtain automatically and I deleted and downloaded the newest drivers from the Acer website twice. I also did a winsock reset and tried to clear the arp cache? One of the issues I am getting when I run the diagnostic is "warn default gateway address could not be resolved via arp". I'm not sure how to resolve that.

Dec 21, 2012I reformat my old PC and installed Win XP SP3. There were no errors during installation and everything works ok. However, I'm not able to connect to the internet with my ethernet cable. The LAN connection shows 'Connected' but properties shows some packets sent but zero received. There are no antivirus program installed, windows firewall is turned off as well.
I've tried the following:
- Tried the same ethernet cable connection to another PC and I was able to get on the internet (so no ISP or router issues I assumed).
- Fix the stack using Winsock - didn't work.
- Device Manager now shows Network Adapter > Atheros L2 Fast Ethernet 10/100 Base-T Controller #2 (no yellow question mark). Although I had to reinstall the driver after XP installation.

Oct 5, 2011I have an HP Workstation that I have been working at constantly to get up and running on the network, it had "OpenCloudSecurity" adaware on it I believe and I was able to get that off with a couple of my freeware tools. The problem I am having is simply it will not connect to the network and only shows. 0Sent 0 Recieved and doesn't pull and IP configuration. I skimmed around and found that sometimes adaware/spyware can play with the TCPIP Stack and that your best bet is to reset the TCPIP stack and WINSOCK ; I did TCPIP Reset and Winsock multiple times with multiple reboots . I know it isn't the ethernet card because I popped in a live Ubuntu CD and it connected just fine on the wired ethernet.

View 2 Replies View RelatedCisco Firewall :: ASA 5510 - Connect From Outside To Conference On MCU / No Video Received
Dec 27, 2011There are two Polycom devices behind ASA (Terminal HDX7000 and MCU RMX1000), ASA is connected to Cisco 1900 router which is connected to ISP.
Polycom devices are NATed (unique global address per device) on router and h323 inspection is done on ASA. The issue is that when trying to connect from outside to conference on MCU I don't receive any video (but MCU shows me like a connected participant). The same is true when MCU try to call outside terminals, they are shown as connected participants, but there is just a black screen. On ASA all ports are opened (both in and out) and there are no ACLs on router. And what means NAT configuration on Polycom devices, why it is needed when NATing is done on router (such configuration option I've seen also on Tandberg and another vendor's devices)?
