Did you ever have a question:
Which switch supports this card?
Which cards does this switch support?
Today, HongTelecom will elaborate on which switches support which cards.
1 Which switch supports this card?
When you doubt which series of switches supports a card, the answer is three words ― see the model. If the card’s name starts with “ES”, this card is supported by the S7700, for example, ES0D0X12SA00.
If the card’s name starts with “EH”, this card is supported by the S9700, for example, EH1D2X12SSA0.
If the card’s name starts with “ET”, this card is supported by the S12700, for example, ET1D2X12SSA0.
However, there is still a lot to know.
– Do all the cards supported by the S7700 have names starting with “ES”?
The answer is no. The S7700 also supports the LE0D0VAMPA00 and cards applicable to all switches.
PS: There are five models of cards applicable to all switches: ACU2, ET1D2FW00S00, ET1D2FW00S01, ET1D2FW00S02 and ET1D2IPS0S00.
– Do all the cards supported by the S9700 have names starting with “EH”?
The answer is no. The S9700 also supports the LE0D0VAMPA00 and cards applicable to all switches.
– Do all the cards supported by the S12700 have names starting with “ET”?
The answer is still no. The S12700 also supports the EH1D2PS00P00 and the ACU2.
The following table gives a summary.
|Product Series||Cards Supported|
|S7700||Models that start with “ES” + the LE0D0VAMPA00 + cards applicable to all switches|
|S9700||Models that start with “EH” + the LE0D0VAMPA00 + cards applicable to all switches|
|S12700||Models that start with “ET” + the EH1D2PS00P00+ the ACU2|
However, do not think that you have known it all. You have to consider the versions.
You don’t have to memorize the detailed relationship between cards, switches and versions. Instead, you just need to look up “Version Mapping” under “Cards” in the Hardware Description.
For example, you can check which versions of the S12700 support ET1D2MPUA000 in the S12700 Hardware Decryption.
In short, the standard answer is:
Question: Which switch supports this card?
Answer: This card is supported by a certain switch since a certain version.
2 Which cards does this switch support?
Switches support two types of cards:
– LPUs: used for receiving and sending data
– Value-added service cards: provide specified services such as firewall, AC and NAT.
I will introduce LPUs and value-added service cards to you respectively.
2.1 Which LPUs do the switches support?
LPUs are used to receive and send data, so the data switching rate is a primary concern. Besides, the features and specifications supported by the LPUs are also important factors.
As highways are divided into expressways, national roads and provincial roads by rate limits, LPUs are divided into 40GE, 10GE, GE and FE interface cards by interface speeds. The following table lists card classifications and product support. (Only LPUs with the most interfaces are listed below.)
|FE interface card||48 x FE||48 x FE||Not supported|
|GE interface card||48 x GE||48 x GE||48 x GE|
|10GE interface card||40 x 10GE||48 x 10GE||48 x 10GE|
|40GE interface card||2 x 40GE||8 x 40GE||8 x 40GE|
As there are special traffic lanes and all-purpose roads, LPUs can be divided into five series by function: F series, S series, E series, B series and X1E series.
As special traffic lanes are divided into lanes for large cars and lanes for medium and small cars, each series falls into three sub-series: A (32K MAC address entries), C (128K MAC address entries) and D (512K MAC address entries). The following table lists card classifications and product support.
|FA, FC LPU||Supported||Supported||Not supported|
|SC LPU||Not supported||Not supported||Supported|
|EA, EC LPU||Supported||Supported||Supported|
|ED LPU||Supported||Supported||Not supported|
|BC LPU||Supported||Supported||Not supported|
2.2 Which value-added service cards do the switches support?
As highways need traffic police and monitoring, networks need security functions such as firewall, IP Security (IPSec), intrusion detection and antivirus.
As highways need traffic controls and traffic lights, networks need specific service functions such as load balancing, Network Address Translation (NAT) and NetStream.
Below, I list value-added service cards supported by switches.
– SPU: provides service functions for switches such as load balancing, firewall, NAT, IPSec and NetStream.
– OSP: can have an operating system and applications installed to support the applications. IPS can be installed on the OSP now.
– ACU: provides functions of a wireless access controller (AC). An ACU installed on a switch can be considered an independent AC connected to the switch in bypass mode.
– NGFW: provides flexible and integrated security functions, such as firewall, NAT, and VPN, for IP networks.
– IPS: provides flexible and integrated security functions, such as intrusion prevention, antivirus, and DDoS attack defense, for IP networks.
The following table lists card classifications and product support.
|SPU||Supported: LE0D0VAMPA00||Supported: LE0D0VAMPA00||Not supported|
|OSP||Supported: ES1D2PS00P00||Supported: EH1D2PS00P00||Supported: EH1D2PS00P00|
|ACU||Supported: ACU2||Supported: ACU2||Supported: ACU2|
|IPS||Supported: ET1D2IPS0S00||Supported: ET1D2IPS0S00||Supported: ET1D2IPS0S00|
