I could see ping loss whenevr i ping to Ip of the phone which is connected on 3750 Switch.
Port is part of data vlan and voice vlan...
interface GigabitEthernet1/0/2
switchport access vlan 10
switchport voice vlan 100
[Code].....
Since Avaya phones do not run CDP, how does the phone know which DHCP pool to pull from to get its IP address if the PC is connected to the phone.
Let's say I have a interface config like this
interface gigabitethernet1/0/1
cisco3750(config-if)#switchport mode trunk
cisco3750(config-if)#switchport access vlan 126
[code]....
And two DHCP scopes configured on the switch. What keeps the phone from pulling from the wrong scope?
I've connected a dslmodem/router to a fast ethernet port(fa0/1) on a 2620 router.There is a 2950 switch connected to the other port (fa0/0).I can ping the Internet via the router but and the switch but not from a host connected to the switch.I can't reach the dslmodem from the host pc.I've configured nat(overload) on the router.

View 12 Replies View Related I'm having some trouble getting my head round the following but I think it's routing related?
I have a Cisco 3750 switch with the following configured:
interface Vlan1
ip address 192.168.0.223 255.255.254.0
no ip route-cache
[Code].....
The 3750 is connected to a firewall which handles the routing. From the 3750 I can only ping remote networks from the vlan1 interface not from vlan6,8 or 10 i.e ping 10.34.37.101 (remote network) source 192.168.0.223 (vlan1) works but ping 10.34.37.101 source 10.74.10.1 (vlan10) does not? I can ping 10.34.37.101 from computers on the various vlans but not from the 3750 it self.
I looked at setting a default gateway for the various vlan interfaces
I have 2 switches. 2960 and 3750. I have trunk on both ports of the switch. there are couple of vlans and ports are assigned to those vlans. examples are management, voice and data. int vlan 1 has ip there is default gateway the hosts are able to connect to the internet when connected to the switch.

I have enable system mtu jumbo on switch to 9000 and on ASR router interface mtu is set to 9114. At switch side switch interface is configured as a trunk port and one vlan has been passed on that interface. I am not able to ping the ip 172.16.10.2 with 9000 mtu size.

View 3 Replies View RelatedAny method of forcing a non connected switch port LED to blink for a certain number of times regardless if there is anything connected.The purpose of this is we have remote 3750 switch stacks and quite often have to tell non technical staff to patch to a certain port. It would be much easier if we could say "Connect it to the empty port which just started blinking orange" as the port numbers are difficult for them to see in these locations.A similar feature is available in the ethtool package for linux which makes it really easy for identifying ports on servers. It would be great if a similar feature is available on Cisco switches.

When I ping my video streaming host's IP address (the IP that they gave me where I can view my IP web camera's video stream), I get anywhere from 0% to 8% packet loss at various times of the day. They're claiming that there's no problem, that this is because this is a router and it's dropping ping packets due to "ping priority giving preference to more important network traffic."

View 3 Replies View RelatedI recently moved from an old apartment in Downtown Montreal, to a suburb area, but still close to where I was before (10 km). I am using the same ISP provider, Videotron. The same speed. I was playing games perfectly fine before, but now something is really wrong. Whenever I join a server, my ping skyrockets up to close to 200, sometimes drifting to 130 but never going below... and often rising back up again.Keep in mind that I filter servers by their pings. I only join servers that display a low ping (although often I won't see any, when I refresh.. there they are). I'll see a server with 30 ping, join it, and be at 200. I'm mainly trying to play Chivalry Medieval Warfare.It's entirely unplayable. Not only is it impossible to properly time parries anymore, but I also get a lot of rubberbanding. I've tested the internet here, and the speeds are accurate. 10 mbps down, 1 mbps up. I am connected to a Linksys E1200 router. I've tried everything I can possibly think of.I went into the router setup, disabled the firewall, added myself to a DMZ, tried to forward every port for steam (although it didn't seem to recognize it as a program)... rebooted the modem, my computer, the router, tried a different Ethernet cable.. nothing is working. It's very depressing. Nothing has changed on my own computer in the move.
View 13 Replies View Relatedabout 4 weeks ago we started experiencing Packet Loss and High Pings while playing games. This affects our 2 PC's and our PlayStation 3 (Since we use them for gaming). We have contacted our ISP several times regarding the issue but each representative we have talked to has had different ideas of what the problem is. They replaced the modem twice which did nothing, so I then purchased 2 new Router's (DIR 601 N150 & DIR 835 N750+). Neither of them solved the issue. my ISP also says it isn't the Internet Cable that is causing the issue. My Download Speeds and Upload Speeds are right where they should be but the ping and the packet loss is the problem. I also contacted DLINK (Router Manufacturer) to see if they had and all we did was upgrade the firmware version and change the Wireless channels which also did nothing. I have plugged this PC into the modem with an Ethernet Cord and played games and all the issues were gone which leads me to believe that Modem and the ISP aren't the issue.
Things I've Tried:
-Resetting the Modem
-Testing each Wireless Channel on my Router
-Enabling and Disabling 802.11n and 802.11g on the router
-Changing the QoS settings
-Installing Software such as Gamebooster and Advanced System Care
-Disabling all Antivirus programs and Firewalls on the PC's
-Using a friends Modem instead of the Cogeco one

I have a switch stack with three WS-C3750X-48 switches running 12.2(55)SE. Recently, stack member 3 went offline for a few minutes, after being online for over a year. A show version on member 3 reports that the system returned to ROM by power-on.
Stack member 3 shares a UPS with a router that did not lose power and all three stack members have stack power with four 350 WATT power supplies between the three of them. There are no crashinfo files on any of the switches, log files show the stack ports on the other switches going offline then switch 3 being removed from the stack.
Surveillance recordings show there was no one near the switch during the time and AAA accounting shows no clues. Is it possible the switch crashed without leaving a trace in the logs, a crashinfo file and report that it returned to ROM by power-on?
I've read before that loose stack cables can cause stack member reboots. Would such an event generate log messages other than the stack ports changing states to down?
I'm facing a problem regarding loss of ping packets when i do ping test from nexus3k to another nexus3k connected directly.however there is no error counters on the interfaces on both of devices.the ping failutre is occurring only whenever i do ping test with a large number of ping packets.I don't see the ping loss symptom with default ping test (default ping test is 5 packets).

I've been having an unusual networking issue lately, where everything runs smoothly apart from when one user's laptop is connected to the WLAN. All users on the network get something between 20% and 60% packet loss, only when this user's laptop is connected. I've made sure all the TCP/IP settings are reset to default, I've reset the router to factory settings, but the problem persists. This only came on recently, and I don't believe anything changed.

View 2 Replies View Relatedthe phone connects to the 3750-A access layer switch (VTP mode client) which connects to the nexus 5596 (The nexus is the layer 3 device and set to vtp mode server) and finally we have a Voice recorder that connects to another access layer 3750-B switch.(VTP mode client)
For voice recording I need to setup RSPAN and the nexus5596 does not support RSPAN will the following have any impact on the nexus
IF I move the 3750-B to VTP server mode and run the command remote span on the VLan I need to Rspan its going to update the VTP data base in short it will update the vlan.dat file for all the switch in that VTP domain.
AS the vtp update reaches the nexus saying there is a change (keeping in mind the nexus does not support rspan not sure hows its going to handle that request and how its going to update its vlan.dat file)
Is it going to incremment the VTP revision number? can it crash the vlan.dat file on the nexus ? or do nothing and ignore the update and stop the update from proceeding to the 3750 A switch?
