No ACL on both 3650 , no firewalls between them , distance is about 2 miles . I tried to make telnet x.x.x.x 1720 or 1719 or 1721 (h323 ports) to opposite switch -connection refused . How can test if ports are open on the 3650 ? Is it coorect If I create allowing acl and apply it on both 3650 on the interfaces connected one switch to voippbx "IN" , second switch on the interf connected to voipphone "IN" ?

View 2 Replies View RelatedI have a above said switch at my remote office (600KM) which is connected with L2 Point to Point leased line. Both the ends I have Cisco 3950 catalyst switches with Vlans configured at both the ends. Now, for obvious reasons I should remove the other end 3950 switch and replace with Cisco 2950 switch. The other end 3950 is having 4 Vlans configured on 4 ports. Now my requirement is, I should configure 3 Vlans (one for P2P, one for 10 Desktops and one for to bring traffic from other network).

I guess switch has no routing.. Before bought that, i thought it is plug and play type. And now having some serious issue which i have to configure via telnet and/or ssh.
View 12 Replies View Relatedhave setup a small lab as per CBTNuggets. Everything was going well until I introduced a second switch to create a trunk. Now I cannot ping between my two switches. Both show operational mode as down:
SWITCH1#show interfaces f0/12 switchport
Name: Fa0/12
Switchport: Enabled
Administrative Mode: trunk
Operational Mode: down
Administrative Trunking Encapsulation: dot1q

I have tried to allow all vlans or vlan 1 specifically and the output of the above doesn't seem to change. I am wondering if there is something in the config-register that is preventing trunking, but I don't really know enough yet!
The output of my second switch is identical to this one, the only difference is that I have it configured as a vtp client.
I have a customers Catalsyt 2950 switch come in for the configuration to be cleaned to factoy default, using the link below removed the customers banner and login information whitch worked

When i restart the switch and enter Enable mode I'm prompted with the password which i used when following the link above,
I want to remove all passwords so when the switch is redeployed to the next site who ever the engineer is that is going to be reconfiguring the switch is able to access privlage mode with out the password promt.
I'm having trouble with a Cisco Catalyst 2950 Series Switch where by I'm following the procedure from Cisco's web site to remove the Banner and login information, url..
Each command is being accepted by the switch from following the information given within the help sheet above,the problem i have now is when i turn the power off then turn the switch back on I'm still getting the banner and login information even though i have follwed Cisco's help correctly.
I am not able to successfully accomplish the password reset function. This 2950 does not respond to the mode button held down at power up or to sending a briak. I have tried both several times and the switch continues to fully boot. [URL]

Using Network Assistant in XP, plugged ethernet cable to first front port and keep getting "Failed to get Default Gateway. Check your security settings to make sure the current Java Virtual Machine is not prevented from running commands.", I have tried reducing secruity to nothing but I still get the same problem.
I also have an official cisco console cable and tried that, but Hyperterminal just does not pick it up when plugged in. I have left the IP dynamic, turned off all netowork adapters apart from ethernet, set the baud rate etc... correctly, still no joy.
how to enable RSTP in the switch (Let's say in 2950 switch).
Or do you have RSTP running in now-a-days switches?
We have a catalyst 2950 switch running:
IOS (tm) C2950 Software (C2950-I6K2L2Q4-M), Version 12.1(22)EA6, RELEASE SOFTWARE (fc1)
This release doesnt have the snmp-server enable traps errdisable command.
Where to look on the cisco site for the next available release for me that would have this command in place?
I have a one 3750x switch and 10 nos of 2950 switch, i want to configuration etherchanel between 3750 to 2950, for that i need 10 nos of etherchanel interface(virtual), but the 2950 switch support maximum of 6 nos of etherchanel port?

My architecture is the same as show on the link with some difference.I use the router 1841 for inetrnet connexion instead of 7200VXR, this router 1841 is connected on the catalyst 3750 port G1/0/1.I use catalyst 2960 instead of catalyst 2950 or 2948.I use ASA 5510 for conexion on remote branche(I have 5 remote site), This ASA is connected on the catalyst 3750 port G1/0/37
Result of the test:
-I can ping devices in the same Vlans
-I can ping devices in different VLANs
-I can ping all device from the catalyst 3750
I cannot ping the router 1841 or ASA 5510 from the any devices (computer)The gateway of each computer is the correpondant VLAN IP address configured on the catalyst 3750.Why I cannot ping the router 1841 or ASA 5510 from the any devices (computer)
I have created a PBR in 3650 switch to route traffic from a specific IP address to a specific next hop or IP address(Router)

I have a 7609 with two LAG groups (Etherchannel not LACP) going to two separate devices that DO NOT participate in spanning-tree (Occam gear if you must know). I'm running 802.1w across the LAG groups but the convergence time is terrible! In essence, the 7609 is running spanning tree against itself (between the two blades). What can I do to fix my configuration?
If I disable the ports on the equipment connected to g1/17 & g1/18, it takes ~30 seconds for spanning tree to start forwarding on g2/17 & g2/18.When I bring the ports back up on the other side of g1/17 & g1/18 which are in a lag group, g2/17 & g2/18 immediately go into block mode while g1/17 & g1/18 start learning for another ~30 seconds!!

I Have a problem I'm trying to configure automatically my switch over ther DHCP when I start the switch it request an IP from the DHCP from here everythings is fine but it does nothing more,indeed I put on my dhcp the option 66 and 67 which is an adress of my TFTP server and a file to download and the switch seems not to understand theses options , I tried my dhcp with a cisco airport and everythings works fine the File from the TFTP is automatically downloaded into the airport...There is an option to add or am I missing something in order to make it work with my switch ?
My switch : Catalyst 2960IOS VER : 12.2(55)SE5
We have a 3750 and a 3560 defined as a layer 2 switches. One gig port on each switch is trunked to layer 3 switches, which containall the VLAN definitions etc. The other gig port on the 3650 and 3750 switches are trunked together to provide an alternative path in the event of a failure.
We have added a new device to the 3750 and given it a VLAN 9, and the VLAN added to allowable VLANS on both trunk ports between the layer 3 and layer 2 devices ie:
switch port trunk allowed vlan 9,10,20,30,40,50,60,90,200,202,206,211,212,700.
From either of the 3750 or the 3560 we can ping any device on any VLAN on any switch in this group with exception ofVLAN 9. We can however ping the ip address of VLAN 9 on the layer three switches.
I have a small network using a 24 port 3750 switch. I need to add five computers in another room and only have one Cat 6 cable running there and no room left on the 3750. I got a 3650 to put in the new room with the new computers. The problem is, whenever I plug the new switch into the 3750, it shuts down the port and gives me an err-disable. I can do a shut/no shut and re-enable the port. I searched the web and read about trunking and clusters. I'm not sure which, if either, is appropriate. I see various documentation that shows you can put one switch behind the other. But nothing tells me the configuration which will allow it.

I have set spanning-tree portfast default on the 4948's. Is it proper to set my uplinks on these switches (g1/1) to shared or does that disable RSTP?
Switch 1 & 2 are 4948's running 12.2(54)
Switch 1 & 2 are connected on port 43
Switch 1 port 1 is connected to the 7609 12.2(33) SRD5 on port g1/2 Switch 2 port 1 is connected to the 7609 on port g2/2
I have a host on Switch 1 port 42 for testing.

View 4 Replies View RelatedI have set up a scenario for a small business and have some questions about how to manage the access between the VLANs. Is there is a better / another way to do it. See the attached picture for the topology / info.
My question is:
My switches is set up with x numbers of VLANs and a routed port (no switch port) to the ASA for internet connectivity. How is the best (or only??) way to manage the access between the VLANs? Is it ACL's on the switch?
And by "managing access" I mean VLAN 50 (public WiFi) only have access to the internet, only management servers have access to management VLAN, Client VLAN only have RDP access to server VLAN and so on. Is there any way to do this in the ASA (or add another (gigabit) router to the topology)) or it the only way to have lots of ACL's on the switch itself? I have thought about "router on a stick", but then I imagine there will be a bottleneck between the switch and the ASA?
(Equipment is 2 x 3650G, ASA5505, AP1252 - see attached file).
I have a question about speed negotiation process between interfaces. I have 3650X Sw and 2960S-48port. All ports of two are GigabitEthernet, however the link between them is only 100Mb/s, Full duplex. I try to set the speed 1000 Mb/s manually in the interface then the interface never up. Its status is down/down. I must set back to speed auto. I show interface Gigabit0/24 in Sw 3650-X and figure out that there are many output drop (over 600000). I clear counter then after two days the output drop is over 70000. This link is trunk link between two switches, all ports of access SW are Gigabit and connect to PC. First, I thinks the 3650X is throttled somewhere in output direction of trunk link. But there is another trunk link (Gi0/23) to another 2960S-48port and no output drop number in this interface. This Giga 0/23 speed is 1000 Mb/s (auto speed, auto duplex)
Does any outside things impact the speed negotiation process between 2 interfaces? And output drop number may caused by abnormal speed between two Gigabit interface?
I just started configuring my cisco catalyst 2950 switch. Basically im preparing for my CCENT exams my basic configuration is as follows.
-My Laptop is connected to the console port
-I'm connected to the internet via my wireless
-I'm connected to the switch port via my NIC card
