# Later to connect to previous screen session
sudo screen -x

Configuring a Range of Interfaces

VLANs Configuration

There are a few rules:

  • A port can be untagged to MAX one VLAN and at least one VLAN, only one VLAN in another word.
  • A port can be tagged to multiple VLAN at the same time.
  • A port can’t be tagged and untagged to the same VLAN.
Types of VLAN Port
  • Aceess: Part of only one VLAN (usually default vlan i.e. VLAN 1)
  • Hybrid: Allow multiple VLANs through. Multiple tagged and untagged VLANs are allowed.
  • Trunk: Allow multiple tagged VLANs through.

Vlan Interface Types [source: fs.com]
PLAN (Private VLAN)

VLANs are used to isolate users in different subnets usually. However, PVLAN is used to isolate users in the same subnet. ISPs uses PVLAN to prevent their users reach to each other.

# ---- [Listing VLANs]
enable
show vlan

# ---- [Creating VLANs]
enable
configure
interface vlan <new VLAN ID>

# ---- [Adding ports to VLAN]
enable
configure
interface vlan <VLAN ID>
untagged gigabitethernet 1/<port number>
untagged gigabitethernet 1/45-1/48
no untagged gigabitethernet 1/<port number>

# Then add to a vlan either tagged ot untagged
Hybrid VLAN
enable
configure
interface twentygigabit 1/29/1
portmode hybrid
switchport

Show Connected Devices

show config

Breakout Ports

show system stack-unit 1 fanout configured

stack-unit <stack number> port <port number> portmode <mode> speed <speed>

# Example with no:
no stack-unit 1 port 3 portmode quad

#<stack number>: 1-6
#<port number>: 1/2
#<mode>: {dual, quad, single}
#<speed>: {100G, 40G, 10G}

# Example:
stack-unit 1 port 1/2 portmode single speed 40G

Example:

  • 1x100G: single and 100G
  • 1x40G: single and 40G
  • 2x50G: dual and 50G
  • 4x10G: quad and 10G
  • 4x25G: quad and 25G

Set an interface to default settings:

default interface twentyFiveGigE 1/3/3
