Etherchannel limitations WS-X4548-GB-RJ45

[jackwikinski]

Hi,

Is anyone aware of any limitation on building an etherchannel on the abovementioned linecard, when bundling more than one port on the same card?

The 4506 is using a 6L-E supervisor engine 12.2(54)SG1.

If it's done on a 6500 with a WS-X6148-GE-TX linecard it affectivley can only reach 1gb throughput.

TIA.

Jack.

Hello Jack,

After going through the documentation I did not find any limitation information on this WS-X4548-GB-RJ45 (just like we could find for WS-X6148-GE-TX)...

I would just pay attention to the distribution of the Etherchannel ports across the different ASIC ports group in the card (as per the 8-to-1 oversubscription) of this classic module WS-X4548-GB-RJ45 ==> Capacity of 6 Gbps (full duplex) connections to the central forwarding engine

WS-X4548-GB-RJ45V:

• Bandwidth is allocated across six 8-port groups, providing 1 Gbps per port group

Specification Summary - Table 3 - Port Information for Line Cards

⁴ The amount of oversubscription can be controlled by varying the number of ports used at 1000 Mbps. All ports can use Gigabit EtherChannel or IEEE 802.3ad for high-speed interconnection applications

Table 4. Product Specifications

EtherChannel technology

• Gigabit EtherChannel: All 1000 Mbps ports • 10 Gigabit EtherChannel: All 10Gbps ports • IEEE 802.3ad (Link Aggregation Control Protocol): All 1000 Mbps ports • Port Aggregation Protocol (PagP): Yes • Number of ports per tuple: 8 • EtherChannel and IEEE 802.3ad technology across line cards: Yes

Hope that helps.

Kind regards.
