Virtual Local Area Network (VLAN)

Create VLAN

Create VLAN 111 name VLAN-MGMT (management VLAN) and VLAN 200 name IDC (access

VLAN).

Then add all switch ports to VLAN 111 and VLAN 200.

Finally, save your job.

ERS-2526T# conf tERS-2526T(config)# vlan create 111 name VLAN-MGMT type portERS-2526T(config)# vlan create 200 name VLAN-IDC type portERS-2526T(config)# vlan configcontrol flexibleERS-2526T(config)# vlan member add 111 allERS-2526T(config)# vlan member add 200 allERS-2526T(config)# save config

Configure VLAN Management

ERS-2526T(config)# vlan mgmt 111

Configure Tagged Ports (Trunk) and Untagged Ports (Access)

Choose port 25,26 as the trunk ports, then add this two ports to Management VLAN.

Port 1 to 24 configure as the access port, and add to VLAN 200

ERS-2526T# conf tERS-2526T(config)# vlan port 26,26 tagging tagAll Pvid 111ERS-2526T(config)# vlan port 1-24 tagging untagPvidOnly Pvid 200

Spanning Tree Protocol (STP)

Spanning Tree Protocol (STP) is a standard protocol used to prevent layer 2 loop issue on the

switched network.

Changing RSTP mode

ERS-2526T# conf tERS-2526T(config)# spanning-tree op-mode rstp

Setup Switch Priority

ERS-2526T# conf tERS-2526T(config)# spanning-tree rstp priority F000

Uplink port Priority

ERS-2526T# conf tERS-2526T(config)# interface fastEthernet 25,26ERS-2526T(config-if)# spanning-tree rstp priority 80

Uplink Port Cost

ERS-2526T# conf tERS-2526T(config)# interface fastEthernet 25,26ERS-2526T(config-if)# spanning-tree rstp cost 100000

Hello Timer, Max-Age, Forward-delay, & tx-holdcount

ERS-2526T# conf tERS-2526T(config)# spanning-tree rstp hello-time 1ERS-2526T(config)# spanning-tree rstp max-age 6ERS-2526T(config)# spanning-tree rstp forward-time 4

ERS-2526T(config)# spanning-tree rstp tx-holdcount 2ERS-2526T(config)# spanning-tree rstp verstion rstp

Uplink p2p

ERS-2526T# conf tERS-2526T(config)# interface fastEthernet 25,26ERS-2526T(config-if)# spanning-tree rstp p2p force-true

Access Port bpdu-filtering

ERS-2526T# conf tERS-2526T(config)# interface fastEthernet 1-24ERS-2526T(config-if)# spanning-tree bpdu-filtering enable

Access port Edge-port

ERS-2526T# conf tERS-2526T(config)# interface fastEthernet 1-24ERS-2526T(config-if)# spanning-tree rstp edge-port true

DHCP Snooping

ERS-2526T# conf tERS-2526T(config)# ip dhcp-snooping enableERS-2526T(config)# interface fastEthernet 1-24ERS-2526T(config-if)# ip dhcp-snooping untrustedERS-2526T(config)# interface fastEthernet 25-28ERS-2526T(config-if)# ip dhcp-snooping trusted

Multicast Protection

ERS-2526T# conf tERS-2526T(config)# vlan igmp unknown-mcast-no-flood enable

Broadcast Protection

Broadcast Protection is used to protect broadcast and multicast traffice.

In this lab configuration, I configured broadcast=20 and multicast=100.

ERS-2526T# conf tERS-2526T(config)# rate-limit broadcast 20ERS-2526T(config)# rate-limit multicast 100
