%ADJ-5-RESOLVE_REQ_FAIL: Adj resolve request failed for
Today I faced an issue where lots of logs " %ADJ-5-RESOLVE_REQ_FAIL: Adj resolve request failed for " are generated on cisco 3750 switch.
It will not impact anything but logs keeps filling the buffer due to which some important logs can be overwritten.
This is due to bug "CSCug43307" in the IOS.
As an workaround use below command to stop these logs.
" no ip cef optimize neighbor resolution "

Difference between POE, POE+ and UPOE
Below is the quick summary of the differences between POE,POE+ and UPOE.
POE is the oldest standard for the devices which can be powered on from the switch. POE enabled switches can only provide upto 15W to the connected devices like phones.
Later on POE+ standard was evolved. Switches which are complied to POE+ standard can provide 30W of power to the connected devices.
Latest standard in this series is UPOE which is not a universal standard but a cisco Proprietary. According to which UPOE enabled switches can provide 60 W of power to the connected devices. Now we can power up not only phones but also PCs/Laptops from the switches.
Below are few more differences.

RJ45 to RJ45 Console Cable
I
saw there is RJ45 to RJ45 console cable is available on Cisco site. It has RJ45 connector at both the ends.
It looks like this:-
But How can we use it?
Can we connect it to our laptop's ethernet port?
Then,
after lot of research I came to know that we cannot use this cable direct with
laptop.
We
have to have a RJ45 to DB9 connector (if DB9 is available on the machine) and
another adaptor DB9 to USB incase DB9 is not available in your machine.
RJ45 to RJ45 cable is used for access server with RJ45 ports
like Digiport server or Blackbox console device to Cisco device connectivity.
The
pinouts for RJ45 to RJ45 console cable is given below:-

Cisco EOL SFP's and its replacement
Cisco has announced EOL notification for many SFPs. Below are the few common Cisco SFPs and their replacement.
Baby Gaint Frame Vs Jumbo Frame...
Frames which are up to 1600 Bytes are called as Baby Gaint.
Ethernet frames from 1600 to 9216 Bytes are known as Jumbo frames.
Ethernet frames from 1600 to 9216 Bytes are known as Jumbo frames.
