I was just going throug one sample configuration n i came across this command
"vlan internal allocation policy ascending"
can some someone please tell me what does this command do n when do we use this command
thanks in advance
yes, these vlans are for internal operation and are not configurable by you and most will not have physical ports associated with them. There could be physical ports assigned to them eg. from one of my switches
SZ-JFH-F00-DTE1#sh vlan internal usage
1006 online diag vlan0
1007 online diag vlan1
1008 online diag vlan2
1009 online diag vlan3
1010 online diag vlan4
1011 online diag vlan5
1012 PM vlan process (trunk tagging)
1013 Control Plane Protection
1014 L3 multicast partial shortcuts for VPN 0
1015 Egress internal vlan
1016 Multicast VPN 0 QOS vlan
1017 IPv6 Multicast Egress multicast
vlan 1018 has the gi3/1 port assigned to it. It is actually the trunk connection between the 2 6500 switches. But this has not stopped me using gi3/1 and i configured that port.
I guess the switch just uses it as a reference.
