Hi All,
I just received two new C9300X-48TX which have optional network module C9300X-NM-8Y installed.
I just cannot make sense of the port numbering and would like someone to explain me this.
Switch has 48 Multigigabit (10G/5G/2.5G/1G/100M) ports.
C9300X-NM-8Y has 8x SFP+ (25G/10G/1G) ports.
When I am listing ports that are in config I see following:
...
Te1/0/47
Te1/0/48
Te1/1/1
Te1/1/2
Te1/1/3
Te1/1/4
Te1/1/5
Te1/1/6
Te1/1/7
Te1/1/8
TwentyFiveGigE1/1/1
TwentyFiveGigE1/1/2
TwentyFiveGigE1/1/3
TwentyFiveGigE1/1/4
TwentyFiveGigE1/1/5
TwentyFiveGigE1/1/6
TwentyFiveGigE1/1/7
TwentyFiveGigE1/1/8
TwentyFiveGigE1/1/9
TwentyFiveGigE1/1/10
TwentyFiveGigE1/1/11
TwentyFiveGigE1/1/12
TwentyFiveGigE1/1/13
TwentyFiveGigE1/1/14
TwentyFiveGigE1/1/15
TwentyFiveGigE1/1/16
HundredGigE1/1/1
HundredGigE1/1/2
HundredGigE1/1/3
HundredGigE1/1/4
When I connected the uplink to this switch, and plugged in Port 1 on C9300X-NM-8Y with 10Gbps SFP, it reported that TwentyFiveGigE1/1/1 is UP and not the expected "Te1/1/1"
Ok, sort of fine as I have seen that port always defaults to the one that technically is the highest speed interface is able to support.
But things that bug me are as followed:
• Why bother with listing Te1/1/1 to Te1/1/8 if a network module is not installed, same applies for the ports HundredGigE1/1/1 to HundredGigE1/1/4?
• Why is switch reporting ports TwentyFiveGigE1/1/9 to TwentyFiveGigE1/1/16 as available when C9300X-NM-8Y only has 8 ports?
Can someone please help me understand this?
