ES3528-WDM Usage of Craft Port

-- This is outband management port. It is refer to port 29 in the CLI

-- It is use for separate the user traffic and management traffic.

-- Please follow the below steps to setup the craft port
1. Create a dedicated management VLAN
2. Configure the management IP address for the switch
3. Add only port 29 to the above VLAN
4. Connect RJ45 from the computer to the craft port
5. Set the same IP address range as switch's IP
6. Now it can either telnet or http to the switch's management


* It is only used for management. It should not carry user traffic. And please note that you can't pass traffic between port 29 and other front ports.

Show RAM and Flash Size for switches

In our switches, we only can check the ram size which "software" used via backdoor. But this is not the actual total size of RAM for switches.

Currently, there is no any CLI command to show the RAM size.

For the FLASH, it can always show by "dir"

SMC8824/48M ACL ListExample

=== Scenario ===

Layer 3 Switch with 4 VLANs:

Vlan 10 : 192.168.10.254/24
Vlan 20 : 192.168.20.254/24
Vlan 30: 192.168.30.254/24
Vlan 40: 192.168.40.254/24

By default, inter vlan routing is enable in the L3 Switch.

Right now, administrator do not want:

VLAN 10 to communicate to VLAN 20 and vice versa
VLAN 30 to communicate to VLAN 40 and vice versa

Port 1-4 ==> VLAN 10, Port 5-8 ==> VLAN20,
Port 9-12 ==> VLAN 30, Port 13- ==> VLAN40

=== Command ===

Prerequisite: Create VLANs, IP address assignment, VLAN assignment

Console#config
Console(config)#access-list ip extended no10to20
Console(config-ext-acl)#deny any 192.168.20.0 255.255.255.0
Console(config-ext-acl)#exit
Console(config)#access-list ip extended no30to40
Console(config-ext-acl)#deny any 192.168.40.0 255.255.255.0
Console(config-ext-acl)#end
Console#
Console#conf
Console(config)#int ethernet 1/1-4
Console(config-if-e1/1-5)#ip access-group no10to20 in
Console(config-if-e1/1-5)#exit
Console(config)#interface ethernet 1/9-12
Console(config-if-e1/11-15)#ip access-group no30to40 in
Console(config-if-e1/11-15)#end
Console#

** This type of scenario recommend to use extended ACL over standard ACL
** IP access-group in must think from the view of port.
Exp: Computer 1 connect to Port 1. Computer 2 connect to Port 2.
When packet from computer 1 send to computer 2, for port 1 consider is IN direction
and for port 2 is OUT direction

SMCGS5/8 QoS Test Report

QoS test report can get from the below link:

SMCGS5

SMCGS8

Please note that it is strictly for internal reference!!

SMCGS5/8 Heat Sink Query

Q: Why SMCGS5 has heat sink but SMCGS8 don't have?

A: GS5 is single solution. The chipset temperature is higher than 70 0C. So we put heatsink on GS5.

But GS8 has two chipsets. The temperature is lower and acceptable. We didn’t put heatsink on GS8. The following is Thermal test result of GS8 for your reference.

SMC87xxML3 CPU Usage Monitoring

The CPU usage only can be view via the backdoor access.

Command as follow:

1. Login to the backdoor
2. Key in the CSC name: SYSFUN
3. Select = 8
4. Enable (1) = 1
5. Select = 8
6. Select = 3
7. To quit, select = 0

SMCWEB-N MAC filter configuration

- Cable connected, ethernet MAC address of machine entered to MAC filter is able to connect to the network. It doesn't matter DHCP server/gateway MAC are add in or not. AP still able to get IP from DHCP server.
- Wireless connected, even wireless MAC is entered in MAC filter, AP is unable to get a IP from DHCP server. User have to add in MAC address of DHCP server, DNS server and Gateway to the MAC filter.

PPPoE Passthrough

When WAN type of ADSL CPE set PPPoE, and client still uses PPPoE dial
connection, then we call it "PPPoE pass-thru". That mean two ADSL connection at the same time through the same modem.
