Troubleshooting Lab and "RULES" of removing config
One thing Im concerned about is the "rules" of TS. Particularly removing config versus alternating config. On some of the practice labs, for example, there are examples where we "alter" an access list, or add a sequence number before another sequence number, and this was a valid solution. However, on other examples there is a policer dropping all traffic, but altering the policer to "transmit" conformed packets is deemed a violation...?
For the most part I get it; in TS dont use the "no" or "default" form of a command unless you are just testing if thats the breakcase, but what if it's required? For example, what if a switch has "shutdown vlan 10", for example, globally?
