One day, one of the DES-3200-28 B1 switches began to write the following in the logs:Continue reading “DDM Port X optic module RX power exceeded the low warning/alarm threshold”
Nothing complicated, just create an ACL rule, due to which on certain ports the switch will drop or pass packets that go to client port 67 from a DHCP server and thus it will not receive IP from unnecessary DHCP servers.Continue reading “Blocking DHCP packets on D-Link DES-38xx”
In 2013, I came up with a primitive solution to the problem with the D-Link DGS-3100 switch, which with an average load can often stop passing traffic through itself.Continue reading “Clearing FDB tables on D-Link DGS-3100 from CRON”
I use the D-Link DGS-3612G switch as an example.Continue reading “Configuring PIM on D-Link Switches”
First, go to the web interface of the access point and look at the “Status” tab of the firmware version.
The default login is admin without a password.
As an example, I will use D-Link DAP-1155 with firmware 1.0.0.Continue reading “D-Link DAP-1155 Firmware Update”
They once asked me the login and password for the docsis modem D-Link DCM-202 to access the web interface, since admin/admin did not fit.Continue reading “Login and password for D-Link DCM-202”
Link aggregation is a technology that allows you to combine several physical channels into one logical channel, which increases the bandwidth and reliability of the channel.Continue reading “LACP. Configuring Link Aggregation on D-Link Switches”
To update the firmware of the D-Link DSL-524T modem, perform the following necessary steps:Continue reading “D-Link DSL-524T Firmware Update”
