  • 1.  Is this VLAN setup correct?

    Posted Jan 24, 2011 07:11 AM

    I've been reading a lot of threads and sites about setting up VLANs and ACLs as we're looking to go towards this setup in the next few months.

    I've set up a test lab scenario with a spare 2810-24 switch (in production it would be a 5406zl) that's aiming to emulate the following setup...

    VLAN1 - default VLAN for switch management
    VLAN100 - standard servers e.g. DHCP, DNS
    VLAN200 - restricted servers
    VLAN3 - standard workstations (access to all)
    VLAN4 - restricted workstations (can't access VLAN200 or VLAN3)
    VLAN5 - printers
    VLAN6 - guest wireless, no access to any VLAN, only to get to Internet gateway
    VLAN7 - internet gateway of firewall

    * DHCP server is 192.168.100.250
    * A10-A15 would be fiber connections to satellite cabinets

    So with that in mind I've come up with this sample config...



    ip access-list standard "PUBLIC_WIFI_ISOLATION"

    remark "BLOCKS GUEST WIRELESS TO ALL OTHER VLANS, ALLOWS INTERNET ACCESS ONLY"

    remark "ALLOW ACCESS TO DHCP SERVER 192.168.100.250"
    10 permit ip 192.168.6.0 0.0.0.255 192.168.100.250 0.0.0.0
    remark "ALLOW ACCESS TO FIREWALL GREEN INTERFACE"
    20 permit ip 192.168.6.0 0.0.0.255 192.168.7.10 0.0.0.0
    30 deny any any



    ip access-list standard "RESTRICTED_SERVER_ACCESS"

    remark "BLOCKS RESTRICTED MACHINES ACCESS TO RESTRICTED SERVER VLAN AND STANDARD WORKSTATION VLAN, ALLOWS ALL OTHER TRAFFIC"

    10 deny ip 192.168.4.0 0.0.0.255 192.168.200.0 0.0.0.255
    20 deny ip 192.168.4.0 0.0.0.255 192.168.3.0 0.0.0.255
    20 permit any any

    vlan 4 ip access-group "RESTRICTED_SERVER_ACCESS" in
    exit

    vlan 5
    name "PRINT"
    tagged A10-A15 (fiber trunk ports to edge switches)
    ip helper-address 192.168.100.250
    ip address 192.168.5.254 255.255.255.0
    exit

    vlan 6
    name "WLAN_GUEST"
    tagged A10-A15
    ip address 192.168.6.254 255.255.255.0
    vlan 6 ip access-group "PUBLIC_WIFI_ISOLATION" in
    exit

    vlan 7
    name "FIREWALL_GREEN"
    untagged A20
    tagged A10-A15
    ip address 192.168.7.254 255.255.255.0
    exit


    EDGE SWITCH CONFIGURATION
    =========================

    hostname "CAB_A_SW01"

    vlan1
    name "DEFAULT_VLAN"
    ip address 192.168.1.2 255.255.255.0
    no untagged 1-22
    tagged 24
    exit

    vlan 3
    name "STANDARD_WKS"
    untagged 1-10
    tagged 24
    exit

    vlan 4
    name "RESTRICT_WKS"
    untagged 11-20
    tagged 24
    exit

    vlan 5
    name "PRINT"
    untagged 21
    tagged 24
    exit

    vlan 7
    name "WLAN_GUEST"
    untagged 22
    tagged 24
    exit



    The main thing I've been trying to make sure is correct is that I've understood the ACL setup correctly in terms of "in" and where the restriction is defined. It seems to be working on the test switch so hopefully all is correct...

    Anyone able to confirm this? Also wondering if I need default gateway setting on the edge switch pointing back to the core switch primary IP address?
