Hi Guys, Finally I am back!! I have
been into Cisco Data Center Technologies from a long time. The first and most
important thing one should know is to get an understanding of how to take
a brief specification information of the Nexus Switches Chassis and I/O Modules
from the names/Model numbers. As I am more into the 7k series switches so I
shall be taking examples of 7k switches
Chassis Identification:
Exact Model number tells two things:
1. Series of Nexus Switch/Chassis
2. Number of Slots in the chassis
For Example the 7k series has
following models.
7004- 7000 Series and 4 Slots
7009- 7000 Series and 9 Slots
7010- 7000 Series and 10 Slots
7018- 7000 Series and 18 Slots
7702- 7700 Series and 2 Slots
7706- 7700 Series and 6 Slots
7710- 7700 Series and 10 Slots
7718 - 7700 Series and 18 Slots
Modules Identification:
Line Card Name will give you a bunch
of information about its specifications. Below is one of the Line Card name
taken as an example:
N77-M348XP-23L
N77 M3 48 X P 23L
N77 / N7K
Its indicates the type of chassis.
N77 is 7700 chassis and N7K is 7000 chassis
M3 / M2 / M1 / F2 / F3
Indicates the series of Linecard.
Detailed comparison chart can be seen on below link:
48
Indicates the number of ports on the
linecard.
X / F / C / G
Indicates the speed of ports:
G is 1 Gig
X is 10 Gig
F is 40 Gig
C is 100 Gig
T / P / S / 2 / Q / K
This will tell you the type of
interface.
T is RJ45
S is SFP
P is SFP+
Q is QSFP+
K is Cisco CPAK
2 is X2
23L
The first digit (2) is the minimum
number of fabric modules required for the card to operate, while the last digit
(3) is the number of fabric modules required for the card to operate at maximum
capacity.
Additionally, if the module has an
additional "L" at the end, it designates that the module is a XL
module. Primarily found on M1/M2 cards, and specifies that the card has
extended hardware ressources (more routes, more MAC addresses etc.).
