JB,
I would recommend the bandwidth command, rather than priority. For
priority, I would expect a requirement that mentions minimal delay or
jitter. Also, the priority will police SMTP to 1.5 M under congestion. I
see no such requirement in the task.
HTH,

Subject: congestion management bandwidth/priority
Hi, I am doing a QoS question that asks to "guarantee at least 1.5Mbps
of the output Queue on the interface"
Using bandwidth:
policy-map SMTP
class SMTP
bandwidth 1500
Rack1R5#sh policy-map
Policy Map SMTP
Class SMTP
Bandwidth 1500 (kbps) Max Threshold 64 (packets)
Using priority:
policy-map SMTP
class SMTP
priority 1500
Rack1R5#sh policy-map
Policy Map SMTP
Class SMTP
Strict Priority
Bandwidth 1500 (kbps) Burst 37500 (Bytes)
What I can see from the output is that both reserve 1500kbps
bandwidth. With the priority however it is guarenteed the LLQ. Do both
of these satisfy what the question is asking for?
TIA
JB
