Dell 3448 & 2848 Tagged Vlan
Hi,
I am using Dell 3448 & 2848 want to know how to setup a Tagged VLAN which is connected to Server. NOT switch or router.
I tried to config Dell 3448 with mode trunk like
#switchport mode trunk
#switchport trunk allowed vlan add 100
or mode general
#switchport mode general
#switchport general allowed vlan 100
Also fail to setup.
Please advise. Thanks!

But it looks the native VLAN also means untagged frames was sent?
and is it allowed to multiple untagged vlans by setting native VLAN?
Thanks!

Hello,
Actually I am using R410 with Broadcom Corporation NetXtreme II BCM5716 NIC and running under CentOS 6.3.
Following is those ifcfg file for reference. How can I trace it is sending untagged or tagged frames?
===========
# cat ifcfg-em1
DEVICE=em1
HWADDR=d4:ae:52:8d:33:40
NM_CONTROLLED=yes
ONBOOT=yes
#IPADDR=
BOOTPROTO=none
#NETMASK=
#DNS2=
TYPE=Ethernet
#GATEWAY=
#DNS1=
IPV6INIT=no
USERCTL=no
# cat ifcfg-em1.100
DEVICE=em1.100
HWADDR=d4:ae:52:8d:33:40
NM_CONTROLLED=yes
ONBOOT=yes
IPADDR=41.52.136.195
BOOTPROTO=none
NETMASK=255.255.255.240
DNS2=41.17.198.1
TYPE=Ethernet
GATEWAY=41.52.136.193
DNS1=41.17.199.1
IPV6INIT=no
USERCTL=no
VLAN=yes
=============
Thanks!

Yes, those server already reboot to apply new network config.
Looks good to identify something after I change it into trunk. Because the server could not access it after changed. Is that means the server is sending untagged frames?

Hello,
Here is part of the config. You can concentrate at e13 config
========when config with native ==========================
console# show running-config
interface range ethernet e(13,25)
dot1x multiple-hosts
exit
interface ethernet e25
port security mode max-addresses
exit
interface ethernet e25
port security max 5
exit
interface range ethernet e(1,13)
switchport mode trunk
exit
vlan database
vlan 100
exit
interface ethernet e13
switchport trunk native vlan 100
exit
interface ethernet e1
switchport trunk allowed vlan add 100
exit
interface vlan 1
ip address 192.168.85.201 255.255.255.0
ip address 41.52.136.39 255.255.255.128
exit
interface vlan 100
ip address 41.52.136.206 255.255.255.240
exit
ip default-gateway 41.52.136.1
mac access-list e25-mac
deny 84:2b:2b:0a:6b:1f
deny 00:00:00:00:00:00
exit
aaa authentication enable default line
aaa authentication login default local
line ssh
==============================
When config as Trunk
interface range ethernet e(1,13)
switchport mode trunk
exit
vlan database
vlan 100
exit
interface range ethernet e(1,13)
switchport trunk allowed vlan add 100
exit
============================
When config as trunk, as mentioned the server which connected to e13 could not communicate with switch vlan 300 interface IP. But I can find it could access to others IP, so I guess it is via vlan 1 to others.
Please check and advise. Thanks!
