Cisco 9300X 12y

[Heraldo Ybiernas]

Hello,

I know this has been asked many times in this group. But I've been scratching my head and pulling my hair. We have cisco 4500x core switch and we've been trying to upgrade that core switch to cisco 9300x 12y core switch. We copied the configuration and everything and we are sticking to the same config and the same ip scheming and all of that. And for some reason.  When we plugged back the sfp modules which is basically 10g we are not getting internet connection.We can ping all the routes, next hop and even the dns server from the switch.But to the idf closets we are not getting ip address.And also I have few questions regarding these switch:

1. On the show ip interface brief command, it shows we have more than 12 ports but physically we have only 12 physical ports.

2.Does our current sfp module which is 10g compatible with the switch we are trying to upgrade which is cisco 9300x 12y.

I'm sorry for my english or grammar.But do enlighten us.

Thanks!

show ip interface brief command, is used for "routed" ports, this includes Loopbacks, VLANS, tunnel interfaces etc., not limited to physical ports!

-> use "show interface status" to show the physical switchports
in combination use "show inventory" to see if the SFP's are properly detected

[Reza Sharifi]

Hi,

In addition to the info Pieterh provided since the physical interfaces could be 1/10/25 or 40, the "sh ip int brief" will list all of them using the same numbering interface. See example:

GigabitEthernet1/1/1 
GigabitEthernet1/1/2 
GigabitEthernet1/1/3 
GigabitEthernet1/1/4 
Te1/1/1 
Te1/1/2 
Te1/1/3 
Te1/1/4 

Also, 10G SFPs from a 4500x should be compatible with 9300.

Are you able to ping the DHCP server (192.168.1.63) from the new switch?

Can you post the output of "sh run" from the new switch?

Hi,

See below. If you are using a 10gig interface to connect to Gigaman, shouldn't the IP address be configured under interface te1/1/1?

If yes, is interface 1/1/1 in up-and-up mode?

Can you post the output of "sh ip int brief"

Also, can you ping the DHCP server from the new switch?

Hello Reza,

That's where trying to figure it out. Physically, the cisco 9300x 12y has 12 ports where it has all the   interface is TwentyFiveGigE. We need guidance on how to connect the Gigaman port to the TenGig port of the cisco 9300x 12y. I am literally pulling my hair on how to connect the Gigaman to the TenGig port.I even flipped the switch if theres a hidden port in the switch.Your guidance is really appreciated. Thanks! 

[pieterh · Accepted solution]

what @Reza Sharifi tries to point out is
that on this platform all  Ten1/1/1 and Twentyfive1/1/1 Hundred1/1/1 are references to the same physical interface (not hidden interface)

instead of changing the speed of the interface configuration to Tengig ,you disable Twentyfive1/1/1 and Hundred1/1/1 and enable Ten1/1/1,
and you use Ten1/1/1 for all further configuration

[Heraldo Ybiernas]

Hello Pieterh,

Thank you for the enlightenment. So in my understanding, the Tengig port and TwentyfiveGig port sits on the same physical port.Its just a matter of configuring that port to communicate to the next hop.We will try this again.And again , thank you for your help. 

[Heraldo Ybiernas]

I'm sorry for being so noob.But quick question.How do you disable TwentyFive 1/1/1, Hundred 1/1/1.And enable the Ten1/1/1.Because everytime I plug in the sfp module the default that will come up is the Twentyfive1/1/1.I already configure the Ten1/1/1 as per y'all recommendation.But still no luck.

[pieterh]

look at commands as described in this document :
Interface and Hardware Components Configuration Guide, Cisco IOS XE Dublin 17.12.x (Catalyst 9300 Switches) - Configuring Interface Characteristics [Support] - Cisco

Step 6	interface interface-id Example: Device(config)# interface HundredGigabitEthernet1/0/25	Specifies the interface to be configured, and enters interface configuration mode.
Step 7	enable Example: Device(config-if)# enable	Enables breakout on an interface.

[pieterh]

Wait a minute..... I noticed something strange.
>>> default that will come up is the Twentyfive1/1/1 <<<
is this really 1/1/1 or should this read 1/0/1 ?

also take a look at this post Solved: Cisco 9300x-12y-a Interface Naming - Cisco Community
where @Leo Laohoo says: 

Depends on the firmware version.  Older version will depend on what optics is plugged in, for example, if a GLC-SX-MMD is connected to port 1 then the interface will be called Gi1/0/1.  Any configuration entered into Ten 1/0/1 or Twe 1/0/1 will not be accepted.  

In later 17.x.x, if the same GLC-SX-MMD is connected to port 1, it is fine for the configuration to be entered in Twe 1/0/1.
