Cisco ASR 920 Seriesmodels
ASR-920-12CZ-A
ASR-920-12CZ-D
1G ports
There are 12*1G ports. The 12*1G ports are grouped as (4 SFP + 8 AMS port)
The first six ports (4 SFP + 2 AMS Port) are non-licensed ports that are enabled by default. The last 6 ports (6 AMS Ports) are licensed ports.
Ports enabled by default: Gi0/0/0 - Gi0/0/5
Licensed ports: Gi0/0/6 - Gi0/0/11
The two ports operate in 1G mode by default and no license is required to activate these ports.
Ports enabled by default: Gi0/0/0 - Gi0/0/1
Licensed ports: None
There are 10*1G ports. These 10*1G ports are grouped as:
Two copper ports
Eight SFP ports
The first four ports (Gi0/0/0 -Gi0/0/3) are non-licensed ports, that is, these ports are enabled by default. The last six ports (Gi0/0/4 - Gi0/0/9) are licensed ports, that is, you need a license to enable them.
There are 24*1G ports. The first 12 ports (Gi0/0/0 – Gi 0/0/11) are active by default and no license is required for these ports. The last 12 ports (Gi 0/0/12 – Gi 0/0/23) are licensed ports, that is, you need a license to enable them.
1G licenses are available in bundles of 6 ports or 12 ports. When a 6-port bundle license is used ports Gi 0/0/12 – Gi 0/0/17 are activated. To activate the remaining 1G ports (Gi 0/0/18 – Gi 0/0/23) a second bundle of 6 ports is required.
Alternately, you can use a 12*1G bundle license to activate all the licensed 1G ports at once.
10G ports
There are 2*10G ports that operate in 1G mode by default. To operate in 10G mode, you have to activate 10 Gigabit Ethernet Upgrade license with single bundle.
Ports enabled by default: Te0/0/12 - Te0/0/13 (operating in 1G mode)
Licensed ports: Te0/0/12 - Te0/0/13 (license needed for 10G mode)
There are 4*10G ports that operate in 1G mode by default. To operate in 10G mode, you have to activate 10 GigabitEthernet Upgrade license with single bundle or two bundles.
When you install and activate with the single bundle (bundle count 1), then the first two ports are enabled in 10G mode (Interfaces Te0/0/2 and Te0/0/3 only).
If you install the second bundle (bundle count 2), all the 10G ports (Te0/0/2 - Te0/0/5) are enabled in 10G mode.
Ports enabled by default: Te0/0/2 - Te0/0/5 (operating in 1G mode)
Licensed ports: Te0/0/2 - Te0/0/5 (license needed for 10G mode available in bundles of 2 ports)
There are 2*10G ports that operate in 1G mode by default. For the ports to operate in 10G mode, you must to activate the 10 Gigabit Ethernet Upgrade License with a single bundle.
Ports enabled by default—Te0/0/10 – Te0/0/11 (operate in 1G mode)
Licensed ports—Te0/0/10 – Te0/0/11 (license needed to operate in 10G mode)
There are 4*10G ports and they are disabled by default. Since dual rate ports are not supported, these ports cannot be used in 1G mode.
To activate the 10G ports, upgrade license with single or two bundles is required.
When you install and activate a single bundle (bundle count=1), the first two TenGigabitEthernet ports are enabled —Te0/0/24 – Te0/0/25.
If you install the second bundle (bundle count=2), all 10G ports (Te0/0/23 – Te0/0/27) are activated.

ASR-920-24TZ-M
Note
In case of the ASR-920-24SZ-IM model, if the pluggable IM (8*1G Copper) is activated, ports 16-23 are disabled and removed from the interface list. Even when all the license bundles are activated before the IM activation, once IM is activated, the ports16-23 will be disabled.
License will remain activated for these ports; however, you must explicitly deactivate/release the port license by executing the (no) license feature port onegig bundle_count command.
In case of the ASR-920-24SZ-IM model, when activating the 8T1/E1 IM, ports Gi 0/0/20 – Gi 0/0/23 are disabled and the interfaces are removed from the list.
