Cisco IOS filtering

In Cisco IOS there are a few ways of filtering IOS output to show only the information you are searching for. For example when looking at the input and output packet counters on an interface you could do one of the below.

Show interface g0/14 | in packets input|packets output
Show interface g0/14 | in packets (input|output)

LAN/WLAN High availability

To ensure you have HA, from your access switches have one etherchannel uplink from the top stack switch and another etherchannel uplink from the bottom stack switch. 

In your wireless environment, spread your access points across all stack switches so if one switch is to fail, you haven’t lost complete wireless coverage. Position acccess points in a way to cater to this.
