Sudden Ping Drop from Default Gateway in VLAN
Hi,
We have a Layer3 Switch 3560 and we have configure multiple VLANs along with SVI on it. We have then cascade layer2 Switches (Cisco 2960) with 3560 by Trunk links. Now we are facing problem on one VLAN that users are in specific VLAN sudden get ping drop from their default gateway (SVI on Cisco 3560) and this problem is not come with all users in that VLAN as just few users in a single time face this problem. When we unplug the systems for few second and reconnect then problem get resolved for few minutes till hours.
Kindly guide me to resolved this.
Regards,
Arshad
I have also clean the arp cache on users systems by using "'netsh interface ipv4 delete arpcache" but in vain. Now i have perform the below steps and operation is working fine since last 20 hours approx.
1- Change the First Casade Switch Cisco 2960.
2- Remove EtherChannel and Change the Backbone port on Cisco 3560 and Cisco 2960.
3- Connect both switches with single backbone Gig Port.
4- IOS Version on previous Cisco 2960 switch was IOS 12.2(50)SE3 and the IOS Version on newly installed switch is IOS 12.2(50)SE5

MacBook Pro keeps dropping WiFi default gateway on Windows 7 Pro
I have to use Windows 7 for most of the work I do on my macbook Pro. I have the 3.2 bootcamp drivers installed, and I'm running Windows 7 Pro 64-bit. The wireless network frequently drops/hangs. Typically it loses the default gateway, and right clicking and doing a repair fixes it. However, I have to do this 6-10 times a day, and it's very annoying.
I contacted Apple support and they say it's a Windows issues, but none of my other non-mac Windows laptops are having this issue and they are connecting to the same wireless access point.
Does anyone have any suggestions since Apple's tech support can't help with this one? I think it has to be tied to drivers for the Wireless device.
Thanks!
--KentI am starting to ask myself why the **** I spent 1000 euros for a machine that is not able to connect to 95% of all the wireless networks I am using. And the best thing is that os x has these wifi related problems for years, so what the **** are the software guys doing the whole day, it cant be that hard to fix something that essential! And if I call them the tell me that its not an osx problem, the routers (which work with android Iphone windows linux ... ) are the problem. I am feeling fooled and start to get angry!!! Somebody with connections to some newspaper news-tv or whats so ever should bring this information out to people that think about getting such a crappy non-working piece of shxx. Maybe then they will stop ignoring this problem - its really ridiculous!!!!!!!!!!!

How to disable inter-VLAN ping response from L3 switch
Correction - This was originally posted for my SG300, but it's actually one of my SGE/2010
I am experiencing an odd behavior from my SG300. When pinging an IP that is in another VLAN (which requires L3 routing), my switch responds if an IP does not exist on the network. For example, let's say I am on subnet A (192.168.0.0) and I want to ping an IP on subnet B (192.168.1.0). If the IP does not exist on subnet B, the SG300 will respond that 'Destination host unreachable'.
You may ask, so what's the big deal? And for the most part I agree, however, there are some circumstances where certain searches on the network falsely identify this as a device residing at that IP. One example is Spiceworks and another is Symantec Endpoint Protection Manager. In both instances, the software is looking for devices to add to inventory and when it receives this 'Destination host unreachable' message from the SG300, it believes something is on that IP.
This problem does not occur if the search is on the same subnet, but only appears when it crosses over to another subnet and routing is involved.
My question is, how do I tell the SG300 to NOT respond with "Destination host unreachable" when an IP does not exist in another VLAN on the switch?
Thanks in advance!The PC10 in vlan 10 can not ping the gateway (10.64.16.1) of vlan 20. It can only ping its own gateway 10.64.8.1
Both hosts are running Windows 7 professional with firewall turned off.
The same for the PC20 in vlan 20. It can only ping its own gateway (10.64.16.1) but not vlan10's gateway (10.64.8.1)
In fact, just for testing purposes.
I temporarily assign g0/1/2 (which was on vlan20) to vlan10 now. Changed the host (PC20) IP to 10.64.8.3.
After this change, the 2 hosts can ping each other (in the same vlan 10)....that's expected. So, the OSes and firewalls issues on the hosts are not the issue. They can ping each other when they are in the same vlan.
However, now that they are in the same vlan, they still can't ping out to G0/0 192.168.0.162.
So, the problem is how to ping from the layer 2 EHWIC to the built-in G0/0 and G0/1 router ports? -
Get Default Gateway Address from BB app
Hi,
I need to get the WIFI default gateway address from an application. I searched in all the forum without a positive result. Some people talks about using WLanInfo but it does not provide the default gateway address.
Can anyone help me?
Thanks!same question as before... are you developing an application?

Alteon Web OS allows you to assign different default gateways for each VLAN. You can effectively map multiple customers to specific gateways on a single switch.
do cisco load balancers support different default gateway for each vlan?one way of doing it today would be to define a serverfarm for each gateway, and have a vserver match_all for every vlan.
For example,
serverfarm gateway_1
no nat client
no nat server
real
x.x.x.x
serverfarm gateway_2
<...>
vserver gateway_vlan1
virtual 0.0.0.0 /0 any
serverfarm gateway_1
vlan
vserver gateway_vlan2
virtual 0.0.0.0 /0 any
serverfarm gateway_2

Some clients get Default Gateway assigned from WRT300N while others don't
Two existing desktops, one wired other wireless and existing laptop wireless connects to internet fine.
Trying to add work laptops, they aquire wireless signal, gets DHCP IP address assigned but doesn't connect. Looked at the ipconfig output and shows no default gateway - router IP is set to 192.168.1.1 - with everything default, I did a reset on it.
The existing machines all have default gateway assigned. Only difference I see is work machines are XP pro. Never had problems with work laptops connecting anywhere else.
Any ideas on how to setup so work laptops can connect?
Solved!

You have configured vmware on your computer to use 192.168.1.1 on the VMnet8 adapter. This means the computer uses 192.168.1.1 itself on that adapter and obviously won't set 192.168.1.1 as default gateway on your wireless adapter because 192.168.1.1 is the computer itself.
Fix your network configuration in vmware. After that a "ipconfig /renew *" or a reboot should obtain a new working lease including the default gateway. Make sure vmware does not use the 192.168.1.0/255.255.255.0 subnet for it's network adapters. -
Default Gateway when connected to VPN
Thanks for reading!
This is probably a dump question so bear with me...
I have set up a VPN connection with a Cisco ASA 5505 fronting internet, with the customers environment behind it (on the same subnet), When connected ot the VPN I can reach the inside Router fronting me and one switch behind the Router (every switch is connected to the router), but nothing else.
My beet is that the Router is messing with my connection, but,, nevermind that!, the setup ain't complete anyway... my question is more related to the Gateway I'm missing when I'm, from the outside, is connected to the VPN on the ASA, could this mess it up? Shouldn't I have a Standard-Gateway in the ipconfig settings in windows?
This is who it looks like now:

: endI didn't realise I had that crypto settings on, thanks my bad!!!
But... the 172.16.12.0 network is directly connected, the Router (that to be honest is a firewall) / switches is all on the same subnet (172.16.12.X/24), so sorry I didn't explain thoroughly, was more wondering about the GW and didn't want to overcomplicate things..
The Firewall/Router dosen't do any routing, so it should work right (I you count out the firewalling in the firewall and so forth, there shouldn't be any problems accomplishing this with the ASA)? The Firewall is more a DHCP for the clients/Firwall for the clients.. this will change in the future.. it will be removed,
the vpn network is staticly routed back to my ASA in that firewall...
I don't like this solution.. but this is who it looks.. for now..
(VPN network is 10.10.10.X/24)
But... shouldn't I see a default gateway under ipconfig when I'm connected to the VPN from internet, on the vpn client that's vpned in, is this correct?
THANKS for all the help! -
Default Gateway address for multiple VPN users/clients
Hello,
We need some help with a VPN setup for a school project.
What we want to do:
We would like to have aprox. 10 different VPN uses that can connect to our Windows Server 2012 R2 which is setup as a VPN server, by the Role called Remote access. And the VPN server is working and we are able to connect to it from another location/computer.
Our current setup:
We have a Cisco router, that are configured with 10 Vlans, from Vlan 10 to Vlan 20, and a managament Vlan called Vlan 100.
The Cisco router is also acting as DHCP server, so inside each Vlan the DHCP gives IP addresses to that specific Vlan, Ex: Vlan 10 has a 192.168.10.0/24 network. Vlan 11 has a 192.168.11.0/24 network, and so on. Vlan 100 has 192.168.100.0/24 This Vlan 100
has connection to all the Vlans.
We have internet connection on the Router on port 0 and each Vlan are connected to the internet.
We have setup the VPN server with a static IP configuration so it is inside Vlan 100 with a Default gateway, like 192.168.100.1 So the VPN server is connected to the internet.
In AD we have created a User and assigned a static IP address in the user properties, under the Dial-In tab. Here we give this user this IP 192.168.10.225
Now when we connect to the VPN server useing this user, we have no connection to any of the Vlans (ping) and no internet. When we in cmd write ipconfig we can see that our VPN connection has this IP 192.168.10.225 but a Subnet called 255.255.255.255 and
a Default gateway called 0.0.0.0
We would like the user to recieve the correct IP settings like: If we connect with our user, it should recieve the IP as it does, but also a subnet called 255.255.255.0 and a default gateway called 192.168.10.1
How is this achieved?
The reason we want this is: We want to create a VPN user for each Vlan. So a user with permission to access Vlan 10 but are not able to see the other Vlans, and then a new user to access Vlan 11 but not able to see the other vlans, and so on.
Hope someone is able to help us to understand how this is done.
Thank you in advance.Hi,
In brief, we can't achieve this. Normally, we would not do this.
Usually, we use firewall or ACL to restrict the remote users.
For example, 192.168.10.100 is assigned to user1 and 192.168.10.101 is assigned to user2. We can use firewall to restrict 192.168.10.100 to access 192.168.10.0/24 and 192.168.10.101 to access 192.168.11.0/24.
Best Regards.

Duplicate IP on a default gateway interface = Bad
I just had an entire VLAN drop out due to a host being brought onto the network that had been erroneously configured with a static IP that happened to be in conflict with the HSRP default gateway IP of the core switch; fortunately, we were able to remove the offending host and reconfigure default gateways as a workaround until the core switch's ARP table updated.
Is there any way to configure a 6500 running IOS to inhibit or block a conflicting IP (especially one with a gateway IP) by using a static ARP entry or other authoritative command?
Thanks,
MarcHi,
You may use the following.
enable Unicast Reverse Path Forwarding on an interface. Unicast RPF guards against IP spoofing (a packet uses an incorrect source IP address to obscure its true source) by ensuring that all packets have a source IP address that matches the correct source interface according to the routing table.
Normally, the FWSM only looks at the destination address when determining where to forward the packet. Unicast RPF instructs the FWSM to also look at the source address; this is why it is called Reverse Path Forwarding. For any traffic that you want to allow through the FWSM, the FWSM routing table must include a route back to the source address. See RFC 2267 for more information.
For outside traffic, for example, the FWSM can use the default route to satisfy the Unicast RPF protection. If traffic enters from an outside interface, and the source address is not known to the routing table, the FWSM uses the default route to correctly identify the outside interface as the source interface.
If traffic enters the outside interface from an address that is known to the routing table, but is associated with the inside interface, then the FWSM drops the packet. Similarly, if traffic enters the inside interface from an unknown source address, the FWSM drops the packet because the matching route (the default route) indicates the outside interface.
Unicast RPF is implemented as follows:
?ICMP packets have no session, so each packet is checked.
?UDP and TCP have sessions, so the initial packet requires a reverse route lookup. Subsequent packets arriving during the session are checked using an existing state maintained as part of the session. Non-initial packets are checked to ensure they arrived on the same interface used by the initial packet.
To enable Unicast RPF, enter the following command:
hostname(config)# ip verify reverse-path interface interface_name

Management port for management switch(2960x) / IP default-gateway for L2 management switch
1)
I am going to connect all mgmt ports of server to this access switch (L2; 2960x) like below. Then I have a management port in 2960x (FastEthernet / L3 port). As you can see below, even though one of Core switch is down, I am able to access through the other Core switch for mgmt SW. Do I need this FastEthernet port of 2960X?
Core Pri ------- Core Sec (Core Pri 192.168.1.2 / Sec 192.168.1.3 / HSRP VIP 192.168.1.1)
mgmt SW ----- (FastEthernet0) ------ Goes to where? I don't have RAS (Remote Access Server)

servers' mgmt ports

2) From server side, server put default gateway (192.168.0.1) so if destination is not known, it dumps all to default gateway. This is L3. I understand this. What about L2 default gateway from switch itself? The L2 access switch supports "ip default-gateway" command. I know that without this command still servers do not have any problems to connect to network. Then this command is for switch (2960x) itself? i.e I log into the switch and ping google.com then switch will try to resolve through DNS, but if DNS is not set up in the switch, it sends all traffic to "ip default-gateway"? Is it right?
3) If L2 (Access) switch has multiple data vlans and mgmt vlan (10.0.0.0/24 10.0.10.0/24 192.168.0.1). Then what will be the "ip default-gateway" for this switch?
Thanks for your time and knowledge.
======================== Reference from Cisco regarding ip default-gateway --------------------------------------
How to configure the ip default-gateway command on a Cisco 3550 series switch
VERSION 2
Resolution
To define a default gateway when IP routing is disabled, issue the ip default-gateway global configuration command. Then, enter the IP address of the next-hop router interface that is directly connected to the switch where a default gateway is being configured.
The default gateway receives IP packets with unresolved destination IP addresses from the switch. Once the default gateway is configured, the switch has connectivity to the remote networks with which a host needs to communicate.
Note: When the switch is configured to route with IP, it does not need to have a default gateway set.
For more information, refer to Assigning the Switch IP Address and Default Gateway.

B2b unable to pick the file from xml gateway
Hi All,
I am taking a scenario where B2B picks the files from xml gateway and drop the files in FTP folder. I modified the XML gateway inbound and outbound, i has given my user credentials(unmae, host ,pwd ,sid, port). In agreement in the place of internal delivery channel i has given XML gateway outbound.
Still its unable to pick the files from xml gateway.
Clarify my understanding please
While b2b picks the files from xml gateway, It will pick from ECX_Inbound or ECX_Outbound?
Here i am attaching the logs:

Internet speed dropped from 2Mbps to 135Kbps for p...
Hi,
Until last week i had 2Mbps internet which was fine and stable, then it suddenly dropped to 135K.
I did not change anything on my network to caus this
I have tried a different router/cables/microfilters and virus checked with avira and malwarebytes none of which did anything so i am convinced it is an external problem.
I called india who reckoned i had 6Meg available.
Please can you find out if anything has changed somewhere else in your network or with my account that would cause this.
here is the speedtest results
Download speedachieved during the test was - 114 Kbps
For your connection, the acceptable range of speeds is 50-250 Kbps.
Additional Information:
Your DSL Connection Rate :6624 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)

Go to Solution.Hi Welcome Your IP Profile has dropped because of a noise issue on your line causing the exchange equipment to see your line as unstable normally the profile will rise within a period of 3/5 days providing there are no restarts on your hub.
Some exchanges are now using a new profiling system that gives 88.2% of your connection speed the profile change on these exchanges is immediate at the new connection speed all you can do is wait while the exchange equipment restores your profile

VRF , Management access only and default gateway
Hello
I am preparing (3) new devices to become my new WAN. The topology looks like,
ASR1002x - Has management int and dg for remote access.
Also has DG to WAN ISP via BGP
3750x stack - Has management int and dg for remote access. (ip vrf management 0.0.0.0 0.0.0.0 (Management vlan hsrp ip))
Also has DG to ASR hsrp - which causes the Management access to drop.
ASA5545x - Has management int and dg for remote access.
Also has DG to ASR hsrp - which causes the Management access to drop.
I MUST KEEP THESE NEW DEVICES OFF THE PRODUCTION NETWORK TO AVOID ANY POSSIBLE ROUTING ISSUES.
I have implemented unique EIGRP instances between the new devices.
These new devices have a management interface so I can access them remotely. I configured the default gateway pointing to the HSRP of the management Vlan and I have remote access.
Obviously I cannot have (2) default gateways out different interfaces, without assigning one with higher admin.
What should my management default gateway look like so I can have remote access to the device and still have the WAN/LAN routing work as needed??found another thread with some suggestions, maybe it helps at the moment.

Best practice to change default gateway for HA-CAM
Hi,
The next week end, i will have a downtime to change it's HA-CAM's default gateway.
My question is, how can i do that?.
This change is not synchronized if i change only from an active cam (service Ip) o it does?
I was thinking on stops services for standby cam, then connect to a service ip, change its default gateway to active cam, then stops services and start them for standby cam and so on...
This is correct or this idea is wrong?
Please, I need suggestions.
Thanks for advance.Kaylan
If the user vlan is routed on a L3 device before going to either the MPLS router or the firewall you could use PBR on the L3 device (if supported).
But as Reza says, we need more info on your network layout.
