Creating vlans on sf300-getting issue to get right configs.
i encounter the following which is related to the above: well i started from scratch and created 3 vlan. vlan 1, vlan 2, vlan 3: management vlan , pc, lap respectively. i connected a pc on port fe 7 and configured for access to vlan 2 only.pc configure with ip 192.168.2.250 /24 gateway 192.168.2.253 Did a ping to 192.168.2.253 and it works fine. Ping 192.168.3.253 as well as 192.168.1.253 and could ping them too. Same done from the laptop whic is found on vlan 3. the issue is: when laptop is on, i can ping the switch 192.168.3.253 (vlan3) from the pc (vlan 2).But as soon as i disconnect the laptop, the pc can not ping the
switch at 192.168.3.253. This happens versa with the laptop. why is it such? i need to configure the pc so that it can not talk with the laptop vlan. can someone please help me. find below my switch sf 300 configure on layer 3 configuration.
All ports attached to VLAN3 are how down and as a consequence the interface route goes away.
This is reflected in the show IP route below, as the interface route for VLAN3 goes down and disappears from the route table.
switch38cbaf#show ip route
Maximum Parallel Paths: 1 (1 after reset)
IP Forwarding: enabled
Codes: C - connected, S - static, D - DHCP
D 0.0.0.0/0 [1/2] via 192.168.20.1 0:4:9 vlan 1
C 192.168.20.0/24 is directly connected vlan 1
This is the reason why you lose pinging ability to VLAN3, or to put it simply something has to be active on VLAN3 for VLAN 3 to respond to a ping or do other processes. This is a normal behavior of Cisco switches.
Again I will reinforce a remember that, the ACL is bound to a switch port. ACL monitors ingress traffic traffic, in other words traffic coming into the switch and then permits or denies traffic according to the ACE entries contained within the access-list.
The switch matches the packets runs through the ACE list from top to bottom , with a implicit invisible (built in ) deny at the end of the list.
