With IEEE 802.1d,recommended consideration when designing the network with STP is not more than 7 hops. On the default timer parameters STP is expected to work fine till 7 hops. Beyond 7 hops the STP will work but it might bit a little hard to predict the behaviour of the STP, which might result in a lots of network problems. From an individual switch perspective like from the root bridge the STP diameter should not be more than 7 hops away.
The limit of 7 hops in the standard was the result of extensive simulations done at DEC in the late 80s, using some fairly delay-sensitive protocols as a benchmark (e.g. LAT). That is the 802.1D standard recommends a maximum bridged LAN diameter of 7 hops, as stated. The issue is more with non-routed protocols (e.g., LAT, LAVc, NetBIOS, etc.) that are somewhat delay sensitive. Having a large number of bridge hops could cause application problems.
We are pleased to announce availability of Beta software for 16.6.3.
16.6.3 will be the second rebuild on the 16.6 release train targeted
towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are
looking for early feedback from customers befor...
