#fail "COMING SOON: Security features, such as SSL and SNMPv3" :( "Creates systems redundancy and increases security" unless you consider ssl and snmpv3 security relevant I guess? Also of interest: "10/100 Mb switched Ethernet" I hope your local-in-pop switch gear has 10/100/1000 and not just 1000 ports. This may be more problematic as the future progresses... (you can't get 100mbps ports on a qfx if I recall correctly, for example) > However I would like to limit the amount of equipment we deploy at a pop, the > majority of our pop's don't have servers...
