Re: Archive Management Config Fetch fails for Aironet 1231
To close this issue out:
It turns out the issue was a Layer 2 firewall.
Although we were using TFTP as the transport protocol, and had permitted it in the firewall, the firewall only permits TFTP on destination port 69. Unfortunately, when LMS does archive management using TFTP, it employs the following sequence (just the relevant part):
1) SNMP_set (which was permitted through the firewall). Note that this initiates the TFTP Write request from the AP
2) TFTP Write request from AP. This write request comes from an arbitrary high numbered source port and is destinted for UDP port 69.
3) LMS responds from port 69 to the arbitrary high port.
4) Firewall blocks this ACK because it doesn't know this port ahead of time.
TFTP transfer fails because AP never hears back from LMS that it's okay to transfer config.
