SOURCE: How do i Reset or break in to get reset my

The resetting of the password requires the installation of a console cable to the console port.

Be sure the terminal emulator program is set to VT-100 management using compatible, 38400 baud rate, no parity, 8 data bits and Console connection one stop bit.

Use the included cable, or be sure that the pin-out complies with a standard null-modem cable

Once the cable is connected, reboot the switch. Type a Ctrl/C until you enter the failsafe mode. This will be denoted with the prompt: “CFE>”
At the prompt execute the following commands:

CFE> passwrd
CFE> reset -sysreset

At this point the password has been reset.

SOURCE: i forgot my admin password

If it's the Power Plus (3C16475BS) model, there should be a reset button inside a small hole on the back. "10 - Recovery Button" Inserting a paperclip or similar to reset. If it's not the Power Plus model and is in fact (3C16475A), this is an unmanaged switch, with no administrative capabilities. You don't need a password.

There is usually a small button on routers that can be accessed with the tip of a pen or a paperclip. When you find that tiny button, hold your pen or paperclip down on it for approximately 10 seconds until the router resets itself to factory defaults.

How Do I Restore the Default VLAN Configuration of an Interface?


We can take S5700-28P-PWR-LI-AC as example.

The default VLAN configuration of an interface involves the default VLAN of the interface and the VLAN that the interface joins. By default, the default VLAN configuration of an interface is as follows:
Access: The default VLAN is VLAN 1, and an access interface joins VLAN 1 in untagged mode.
Trunk: The default VLAN is VLAN 1, and a trunk interface joins VLAN 1 to VLAN 4094 in tagged mode. That is, a trunk interface allows all VLANs.
Hybrid: The default VLAN is VLAN 1, and a hybrid interface joins VLAN 1 in untagged mode.
Dot1q-tunnel: The default VLAN is VLAN 1, and an dot1q-tunnel interface joins VLAN .1
Negotiation-auto or Negotiation-desirable: If the interface is negotiated as an access interface, the default VLAN configuration of the interface is the same as that of the access interface. If the interface is negotiated as a trunk interface, the default VLAN is VLAN 1 and the interface joins VLANs 1 to 4094 in tagged mode. That is, the interface allows all VLANs.
Run the display this include-default ' include link-type command in the interface view to check the link type of the interface, and then perform one of the following configurations to restore the default configuration of the interface.
Restore the default VLAN configuration of an access or dot1q-tunnel interface.

I want to block internet access on a particular port of D- Link Switch


Hi there.

Unfortunately your switch is what is known as an "unmanaged" switch meaning you cannot make changes to it in any way. It is simply a plug and go device. If you want a switch that can control internet access you would be better off buying a "managed" switch or a switch that supports something called a "VLAN". A VLAN is a technology where you can make certain ports part of a virtual network and you can restrict certain access on these virtual networks such as internet access.

If it is a certain computer that you want to block internet access to you can possibly do that though your router's firewall's configuration.

Sir I have 4200 series 26 ports Switch i want to Configure intra VLAN But I am Getting a problem to Configure that switch . After Cnfigure VLAN on Consol prompt. I am not accessing to my Server & WAN...


Hi,
If you are creating only Layer 2 VLANs on the switch , you wont be able to ping the servers and Routers as they are in default VLAN1.
you can do the below steps
1. Create sub interfaces on the router LAN interface
2. Provide a new ip range to the new sub interface
3. Make the switch port connecting router as trunk, so that it will carry both the VLAN info
4. on your Labtop/PC give the IP address in the newly defined range
5. Make your switch port to be in the new VLAN

This will work , if you wont be able to configure the above settings, let me know i will give you the detailed config

ZyXEL IES-1000 with AAM1212 ADSL 12 port module step-by-step guid


Going through the GUI would take too long, so use CLI to add the commands below. After that, check the GUI and see how those changes appear.

VLANs:
On all equipment use 802.1q tagging. The example below puts adsl ports 1 to 10 in vlan10 and ports 11-12 in vlan2. These vlans are 802.1q tagged on the ethernet ports.

switch vlan set 1 1~12:X enet1~enet2:FT DEFAULT
switch vlan set 2 1~10:X 11~12:FU enet1~enet2:FT VLAN2
switch vlan set 10 1~10:FU 11~12:X enet1~enet2:FT VLAN10
switch vlan set 17 1~12:X enet1~enet2:FT VLAN17
switch vlan pvid 1~10 10
switch vlan pvid 11~12 2
switch vlan pvid enet1~enet2 1
switch vlan priority * 0
switch vlan gvrp * disable
switch vlan frametype * all
switch vlan cpu set 1

ATM circuit:
Each port requires one or more VPI/VCI circuit. You could map different circuits to corresponding vlans. The config below creates a primary circuit 1/35 on each port. On ports 5 and 9 is another circuit 1/32 mapped to vlan10

adsl pvc set * 1 35 super DEFVAL
adsl pvc set 5,9 1 32 10 0 DEFVAL

Remember a dslam is just a switch, bridging packets from a VC onto a VLAN or straight onto ethernet.

Router no connecting to the internet


You need to configure NAT on the router to permit the entire LAN to access internet

Example.
LAN Segnment is 192.168.1.0/24

1. Create an access-list to identify the local segment

2. Configure the Nat interfaces properly (NAT-INSIDE, NAT-OUTSIDE)

3. do the NAT configuration

i.e ip nat inside source list (ACLNUMBER) .....

Cisco error on switch


%SYS-4-P2_WARN: 1/Tag 0 The switch generates %SYS-4-P2_WARN: 1/Tag 0… messages.
This example shows the syslog output that you see when this error occurs:
%SYS-4-P2_WARN: 1/Tag [dec] on packet from [ether] port [chars],
but port's native vlan is [dec] This message indicates that an 802.1Q-tagged packet was received on a nontrunk port. The VLAN that is derived from the packet tag is different from the port native VLAN. In the error message:
  • The Tag [dec] is the VLAN identifier from the packet.
  • The [ether] is the host MAC address.
  • The port [chars] is the port identifier.
  • The second [dec] is the native VLAN number.
There is a possibility that the local port is incorrectly configured as an access port instead of a trunk port. Alternately, the remote side can have been configured as a trunk port instead of an access port.
Verify that the local port is not incorrectly configured as an access port instead of a trunk port. Also, verify that the remote side is not configured as a trunk port instead of an access port.
