OmniSwitch 9000
• Network Rule
• Protocol
Max. no. of 1x1 STP instances supported per system 253
VLAN Port based, IEEE 802.1Q VLANs 4.1.11
Advanced VLAN Classification: MAC, protocol, IP subnet
IEEE 802.1ad VLAN Stacking (aka Q-in-Q)
Maximum VLANs 4.2.15 VLAN Range Support
Up to 4094 VLANs for Flat Spanning Tree mode/MSTP and 253 VLANs for 1x1 Spanning Tree mode
are supported. In addition, it is now possible on the OmniSwitch 6800/6850/9000 to specify a range of
VLAN IDs when creating or deleting VLANs and/or configuring VLAN parameters, such as Spanning
Tree bridge values.
VLAN Stacking The IEEE 802.1Q-in-Q VLAN Tagging purpose is to expand the VLAN space by tagging the tagged
packets, thus producing a "double-tagged" frame. The expanded VLAN space allows the service
provider to provide certain services, such as Internet access on specific VLANs for specific customers,
and yet still allows the service provider to provide other types of services for their other customers on
other VLANs.
Maximum frame size
With the insertion of a 4-byte svlan tag by VLAN Stacking, the maximum frame size that can be
accommodated is jumbo frame size less 4 bytes = 9216 – 4 = 9212 bytes.
Maximum number of SVLANs:
•For port level VLAN Stacking: 4093 (VLAN 2 through 4094).
•For port / vlan level VLAN Stacking: 768 (can use any number from 2 through 4094 inclusive).
VLAN Tag Translation
(aka “VLAN Tag Overlapping”)
VLAN Tag Translation is supported.
Maximum number of BPDUs the switch can handle Approximately 800 BPDUs per second
MAC Address Table In synchronized mode (default), up to 16K MAC Addresses is supported per system
In Distributed mode, up to 64 K MAC Addresses is supported per system (no more than 16K per NI).
1K (authenticated / mobile users) per system
Latency: <10µsec
L2 MAC Address Table Size Enhancement
AOSv6.1.3r01 Release
There are now two source learning modes available for the OmniSwitch 9000 Series switches:
synchronized and distributed. By default the switch runs in the synchronized mode, which allows a
total MAC address tables size of 16K per chassis. Enabling the distributed mode for the switch
increases the table size to 16K per module and up to 64K per OmniSwitch 9000 chassis.
The 6.1.3.R01 release provides support for this feature on the OmniSwitch 9000 Series; increasing the
MAC address table size is not supported on the OmniSwitch 6800 Series and OmniSwitch 6850 Series.
IP Address Table Routes 40K routing table
12K forwarding LPM entries, 8K hosts entries per module
Latency: <10µsec
Layer-2 Table Hashing The L2 Table size is 16K entries. This is organized as 2K buckets with each bucket having 8 entries.
The search key for the L2 Table is the 60 bit (i.e. 48-bit DA MAC address + 12 bit VLAN-ID) in the
Ethernet MAC header in the incoming flow. The key is hashed into a 11-bit value used to select the
bucket in the table using a CRC32 lower 11-bits algorithm. Each entry in the selected bucket is
compared with the key. The match must be an exact match since if it does, it must be a host MAC
address entry. If the key matches an entry in the bucket, then the information in the entry is used in the
ingress logic for the destination port

Max number of configured VLANs per port 1 K (1,024) with support of full 4K IEEE 802.1Q VLAN Spectrum. Port based (w / IEEE 802.1Q)
VLANs.
The switch has indeed been tested with up to 4,094 active VLANs as well, but this is really based on
switch configuration and available resources. Otherwise, the more practical, or more realistic and/or
recommended one is the 1,024 active VLANs.
A-VLAN Maximum number of Avlan authenticated user per system: 1024.
The system supports up to 1024 authenticated/mobile Mac-addresses
AVLAN supports RADIUS or LDAP as authentication servers. By configuring multiple servers, user
can gain server failover in case of server outage.
