Ahoj,
chtel bych Vas vsechny poprosit o radu. Mam router na FreeBSD:
FreeBSD legolas 5.5-RELEASE-p11 FreeBSD 5.5-RELEASE-p11
K routeru je pripojen switch Cisco 2950-12. Do switche jsou
pripojeny dalsi dve zarizeni (dalsi PC router a HW AP). Na routeru
a switchy mam nastavene VLANy. Konfigurace na FreeBSD:
do jadra jsem pridal:
device miibus # MII bus support
device vlan # VLAN support (needs miibus)
pouzita sitova karta:
em0: <Intel(R) PRO/1000 Network Connection, Version - 1.7.35>
port 0xdc80-0xdcbf mem 0xff040000-0xff07ffff,0xff0a0000-0xff0bffff
irq 10 at device 14.0 on pci0
em1: <Intel(R) PRO/1000 Network Connection, Version - 1.7.35>
port 0xdc40-0xdc7f mem 0xff000000-0xff03ffff,0xff080000-0xff09ffff
irq 11 at device 14.1 on pci0
nastaveni v /etc/rc.conf:
cloned_interfaces="vlan1 vlan50 vlan100"
ifconfig_vlan1="inet 10.94.1.1 netmask 0xffffffe0 vlan 1 vlandev em1"
ifconfig_vlan50="inet 10.94.1.33 netmask 0xffffffe0 vlan 50 vlandev em1"
ifconfig_vlan100="inet 192.168.100.1 netmask 0xffffff00 vlan 100 vlandev em1"
ifconfig_em1="up"
Do vlany50 je pripojen PC router, do vlany100 HW AP a vlan1 je management,
kde je nastaven management switche Cisco. Nastaveni FreeBSD jsem provedl
podle navodu na http://people.freebsd.org/~arved/vlan/vlan_en.html.
Zarizeni na vlane50 i vlane100 jsou dostupna a vse funguje podle toho jak
jsem pozadoval. Jediny problem je s vlanou1. Na management switche se neni
mozne pripojit. Switch neni dopingatelny a ani ze switche nic nedopingam.
Zde je nastaveni Cisco switche:
no service pad
service timestamps debug uptime
service timestamps log uptime
service password-encryption
!
hostname cisco-sw
!
enable secret 5 xxxxxxxxxxxxxxxxxx
!
ip subnet-zero
!
spanning-tree mode pvst
no spanning-tree optimize bpdu transmission
spanning-tree extend system-id

end
Jak je videt z konfigurace switche, tak na portu 1 je PC router
(vlana 50), na portu 2 je HW AP a port 12 je nastaven jako trunk
a je pripojen do em0 na FreeBSD routeru.
Nekde je v te vlane1 problem nebo mam nekde chybu v konfiguraci
(pokusil jsem se nakonfigurovat nejake zarizeni, kteremu jsem dal
IP adresu z vlany 1. Zarizeni take nebylo dostupne). Bohuzel tu
chybu nemohu najit, tak bych Vas chtel poprosit o radu. Predem
Vse moc dekuji za reakci na muj dotaz.
