lldp_tick counted main-loop passes, so the 6000 meant for 30 s at SYS_TICK_HZ ran at whatever rate the loop happened to have, and the interval moved with httpd and SFP load. Step once per second from the tick counter like the STP timers do, count seconds to the interval and derive the TTL from it with the 802.1AB hold multiplier of 4.
