in TSHOOT topology, we have a DHCP client (client1) on vlan 10. Broadcast traffic from the client to the DHCP server should be allowed to pass through DSW1 and DSW2. So where to put “ip helper-address”? it depends on which switch will take the HSRP Active state. First, check the spanning-tree instance on vlan 10. Then, see which is the HSRP Active gateway. If for example DSW1 is the Active HSRP, then “ip helper-address AddrA” should be put under “interface vlan 10” of DSW1. Beware that AddrA is the ip address of R4 interface. And this value is: – 10.1.4.6, if DSW1 is HSRP Active gateway, – 10.1.4.9, if DSW2 is HSRP Active gateway. This took me an hour or so to figure out, maybe because I’m a little tired :-)

Two days are left before I sit for my TSHOOT exam. I feel confident about it since I have a first taste of it: I read feedback given by test takers that it was a nice experience. I practiced the official Cisco TSHOOT topology on GNS3 with different protocols. I ought to be ready for both scenarios: – If I succeed, then I know that all my limiting beliefs about CCNP were wrong. I would know that I was prisoner of my false beliefs. – If I fail,  I should remind myself about all the courageous people in the world who spent a lot of money and time in the pursuit of their certs.   Either way, I’ll learn something, and that’s my own choice. I made my choice to enhance my career, no matter what the sacrifices are. “Courage is resistance to fear, mastery of fear – not absence of fear” – Mark Twain

Breathing is taken for granted and most people think it comes naturally and from the chest. In fact, I myself thought that the lungs push the chest upwards, which explains the chest movement up and down. But as hard as we try to breathe the conventional way we tend to feel “tired” from breathing at the end of a work day especially if you are like me a network engineer or a person who is sitting for a long time in a desk/office. And you probably experience the following symptoms: sense of culminated stress sense of fatigue/drowsiness at the end of the day loss of appetite. I tried one day and I practiced deep breathing the whole day. I mean, inhale slowly with my nose until my lungs are full and exhale totally through my mouth until my lungs are “empty” and my stomach is stressed. Does it have benefits? I totally agree: – I felt more focused on what is most important to me at one time, – I could work steadily without feeling tired, – I did not fe...

dot1x – dot1x can work with DHCP address assignment – only EAPOL is allowed before a port is authorized – Vlan Assignment (by a RADIUS server) depends on the result of dot1x authentication – RADIUS server- the dot1x authentication server- is the one which verifies the identity of the client connected to a dot1x port AAA – there are named method lists (simply method lists) – once AAA is enabled, the default method list is applied to console, VTY access, enable mode…
