This read-only value reports the minimum VCI the signalling stack may currently allocate to switched virtual channel connections, computed as the maximum of this interface's own configured minimum and its peer's, or a fixed value if not negotiated. Because it's the maximum, not the minimum, of the two sides' configured floors, the more restrictive of the local and peer settings wins, so it reveals whether the peer is actually enforcing a higher VCI floor than this switch's own configuration would otherwise allow. A local floor of 32 combined with a peer that insists on reserving VCIs up to 63 would leave this object reading 64, meaning no SVCC on this interface can actually be assigned below VCI 64 despite the local configuration alone permitting it.
