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

SMC8824/48M Routing Table and Host Size

The max entry is 256 entries

the max host is 2K.

SMC289xW VAP Option Grey Out

When SMC2890/1 set to bridge mode, it only can use one VAP. All other three VAPs will be Grey out.

In order to use all four VAPs, the SMC289xW must set to AP mode.
